While signing in to a Microsoft account, Microsoft 365, Outlook, OneDrive, Teams, Windows, or another Microsoft service, you may encounter a message such as:

“We need to verify your identity.”

You may also see similar messages:

• “Help us protect your account.”
• “Verify your identity.”
• “We need to make sure you’re you.”
• “Approve sign-in request.”
• “More information required.”
• “Your organization needs more information to keep your account secure.”
• “Additional verification required.”
• “We couldn’t verify your identity.”
• “Your account or password is incorrect.”
• “Your sign-in was blocked.”
• “You need to verify your account before continuing.”

In many cases, this is a legitimate Microsoft security mechanism rather than an error. Microsoft may request additional verification when it detects a new device, unusual location, changed password, expired authentication session, security-policy requirement, or potentially risky sign-in.

However, if the verification request appears repeatedly or you cannot complete it, there may be a problem with authentication methods, browser cookies, Windows credentials, Microsoft Authenticator, Conditional Access, device registration, account security information, or Microsoft 365 administrator settings.

This article explains the common causes and provides a systematic troubleshooting procedure.

1. What Does “We Need to Verify Your Identity” Mean?

Microsoft uses identity verification to confirm that the person attempting to access an account is actually the account owner.

Depending on the account configuration, Microsoft may ask you to verify yourself using:

• Microsoft Authenticator
• SMS verification code
• Phone call
• Alternate email address
• Security key
• Passkey
• Windows Hello
• PIN
• Fingerprint
• Face recognition
• Temporary Access Pass
• Organization-approved authentication method

For Microsoft 365 business accounts, additional requirements may also be imposed by the organization through Microsoft Entra ID security policies.

2. Where Can This Message Appear?

The verification request can occur in several Microsoft products and services, including:

• Windows 10
• Windows 11
• Microsoft 365
• Office applications
• Outlook
• Outlook on the web
• OneDrive
• Microsoft Teams
• SharePoint
• Exchange Online
• Microsoft Store
• Microsoft Edge
• Microsoft Entra ID
• Azure services
• Microsoft account portal
• Windows Settings
• Work or School account sign-in

The exact troubleshooting procedure depends on where the verification prompt appears.

3. Common Reasons Microsoft Asks You to Verify Your Identity

New Computer or Device

Signing in from a computer, smartphone, tablet, or browser Microsoft has not previously recognized can trigger additional verification.

This is normal security behavior.

New Location or IP Address

Microsoft may request verification when the account is accessed from a significantly different location or network.

Examples include:

• Home to office network
• Office to mobile hotspot
• Different ISP
• VPN connection
• Proxy server
• Remote Desktop server
• Cloud-hosted Windows server
• Traveling to another city or country

Password Recently Changed

After changing the Microsoft account or Microsoft 365 password, existing authentication tokens may become invalid.

Applications such as Outlook, Teams and OneDrive may request authentication again.

Multi-Factor Authentication Is Enabled

If MFA is enabled, entering the password alone may not be sufficient.

Microsoft may require another authentication factor, such as:

Password + Microsoft Authenticator approval

or:

Password + SMS verification code

4. Microsoft Authenticator Problems

Microsoft Authenticator is one of the most common verification methods used with Microsoft accounts and Microsoft 365.

Verification can fail if:

• Authenticator was removed
• Phone was replaced
• Authenticator was reinstalled
• Account was deleted from Authenticator
• Push notifications are disabled
• Internet connectivity is unavailable
• Time/date synchronization is incorrect
• Authentication method registration is outdated

If the Authenticator notification does not arrive, select another available verification method when Microsoft offers one.

5. Check Internet Connectivity

Before performing advanced troubleshooting, verify that the computer has stable Internet connectivity.

Open several websites in the browser.

If the Internet connection is unstable, authentication requests may time out.

Also temporarily disable, where appropriate:

• VPN
• Proxy
• Aggressive web filtering
• Third-party firewall rules
• DNS filtering

Then retry authentication.

Do not permanently disable organizational security controls without authorization.

6. Verify Computer Date and Time

Incorrect system time can interfere with authentication tokens and secure HTTPS communication.

In Windows 11:

Settings → Time & language → Date & time

Enable:

Set time automatically

and preferably:

Set time zone automatically

Then select:

Sync now

After synchronization, restart the affected Microsoft application and test again.

7. Try Signing In Through a Browser

Before troubleshooting Outlook, Teams, OneDrive, or Office, determine whether the account itself works.

Open a browser and try signing in to the appropriate Microsoft account or Microsoft 365 portal.

If browser sign-in succeeds but Outlook or another desktop application fails, the problem is probably related to the local application, cached credentials, authentication tokens, or Windows profile.

If browser sign-in also fails, investigate the account, password, MFA method, security information, or administrator policies first.

8. Try an InPrivate or Incognito Browser Window

A corrupted browser session can cause repeated verification prompts.

Open:

Microsoft Edge → InPrivate

or:

Google Chrome → Incognito

Then try signing in again.

If authentication works in private browsing mode, cached cookies, browser extensions, or existing Microsoft login sessions may be causing the problem.

9. Clear Microsoft Login Cookies

Old or corrupted cookies can create authentication loops.

You can clear cookies associated with Microsoft sign-in services.

Be aware that clearing cookies may sign you out of Microsoft websites and other services.

After clearing the relevant browser data:

1. Close all browser windows.
2. Reopen the browser.
3. Sign in again.
4. Complete verification.
5. Check whether the verification loop has stopped.

10. Try Another Browser

If the verification page fails in one browser, test another current browser.

For example:

• Microsoft Edge
• Google Chrome
• Mozilla Firefox

If authentication works in another browser, investigate the original browser's cookies, extensions, privacy settings, or security software.

11. Check Microsoft Account Security Information

For a personal Microsoft account, review the security information registered with the account.

Verify that your:

• Mobile number is correct
• Recovery email is accessible
• Microsoft Authenticator is configured
• Old phone numbers are removed where appropriate
• Unknown authentication methods are investigated
• Security information is current

Do not remove your only working authentication method before adding and testing a replacement.

12. Check Microsoft 365 Authentication Methods

For a business or organizational Microsoft 365 account, authentication methods may be controlled through Microsoft Entra ID.

Depending on permissions and organizational policy, available methods may include:

• Microsoft Authenticator
• Phone
• SMS
• FIDO2 security key
• Windows Hello for Business
• Temporary Access Pass
• Passkeys
• Other organization-approved methods

If the user's registered method is no longer accessible, an administrator may need to assist with authentication-method recovery or re-registration.

13. “More Information Required” Message

Microsoft 365 users sometimes receive:

“More information required.”

This usually indicates that the organization requires the user to configure additional security information.

The user may need to register:

• Microsoft Authenticator
• Mobile phone
• Alternative authentication method
• Security key
• Another method required by organizational policy

This is not necessarily an error.

It can be part of the organization's security registration process.

14. Microsoft Authenticator Number Matching

Some Microsoft Authenticator sign-ins use number matching.

Microsoft displays a number on the login screen.

The user must:

1. Open Microsoft Authenticator.
2. Select the sign-in notification.
3. Enter or select the number displayed by Microsoft.
4. Approve the request.

Never approve an Authenticator request you did not initiate.

An unexpected approval request may indicate that somebody else is attempting to access the account.

15. Phone Changed or Lost

If the registered phone has been replaced, lost, reset, or damaged, Microsoft Authenticator may no longer work.

Look for options such as:

“I can't use my Microsoft Authenticator app right now”

or:

“Sign in another way”

If another authentication method has already been registered, use it.

For organizational accounts, contact the Microsoft 365 or Entra administrator if no usable verification method remains.

16. Re-register Microsoft Authenticator

If Authenticator is malfunctioning, re-registration may resolve the issue.

However, proceed carefully.

Before removing the existing Authenticator registration, make sure there is another working authentication method or that an administrator can recover the account.

A typical process is:

1. Add or verify a backup authentication method.
2. Remove the obsolete Authenticator registration.
3. Add Microsoft Authenticator again.
4. Scan the QR code.
5. Complete the test approval.
6. Verify that sign-in works.
7. Remove obsolete phone registrations if appropriate.

17. Repeated Verification Prompt in Outlook

If Outlook repeatedly asks for identity verification while browser sign-in works normally, cached authentication information may be corrupted.

Possible causes include:

• Old Windows credentials
• Expired authentication tokens
• Password recently changed
• Office activation problem
• Corrupted Outlook profile
• Account configuration issue
• Organizational authentication policy

Start with the least disruptive troubleshooting steps before rebuilding the Outlook profile.

18. Remove Old Credentials from Windows Credential Manager

Windows Credential Manager can contain old Microsoft or Office credentials.

Open:

Control Panel → Credential Manager → Windows Credentials

Review entries associated with the affected Microsoft, Office, Outlook, Teams, or organizational account.

Remove only credentials that you understand are related to the affected account.

Then:

1. Close Office applications.
2. Restart Windows.
3. Open the application again.
4. Sign in using the current credentials.

Avoid indiscriminately deleting all stored credentials, especially on business computers.

19. Disconnect and Reconnect Work or School Account

For organizational accounts, check:

Settings → Accounts → Access work or school

Select the affected account and inspect its status.

Disconnecting and reconnecting the account can resolve some registration problems, but this should not be the first troubleshooting step on organization-managed devices.

Disconnecting a work account may affect:

• Microsoft 365 access
• OneDrive
• Teams
• Device management
• Company policies
• Certificates
• Single sign-on
• Intune management

On managed systems, consult the administrator before disconnecting the account.

20. Check Office Activation

Identity verification may sometimes be related to Microsoft 365 licensing or Office activation.

Open Word or Excel and check:

File → Account

Verify:

• User is signed in
• Correct account is displayed
• Product is activated
• Subscription is active
• No activation warning appears

If the wrong Microsoft account is connected, sign out of the incorrect account and authenticate with the licensed account.

21. OneDrive Verification Loop

If OneDrive repeatedly requests authentication:

1. Verify browser sign-in first.
2. Check Internet connectivity.
3. Confirm correct system date/time.
4. Restart OneDrive.
5. Sign out and sign back in if appropriate.
6. Check Windows Credential Manager.
7. Check the Work or School account connection.
8. Reset OneDrive only if simpler fixes fail.

Before resetting or unlinking OneDrive, confirm that important files have synchronized successfully.

22. Microsoft Teams Verification Problems

Teams authentication problems may occur because of:

• Expired tokens
• Changed password
• Multiple Microsoft accounts
• Cached sign-in information
• Conditional Access policies
• Device compliance requirements
• MFA registration problems

First test the same account through a browser.

If web access works, troubleshoot the Teams application and cached account session.

23. Multiple Microsoft Accounts Can Cause Confusion

Many users have several Microsoft identities, for example:

Personal account:
user@outlook.com

Business account:
user@company.com

Sometimes the same email address can also be associated with different Microsoft account contexts.

Make sure you select the correct:

Personal account

or:

Work or school account

when Microsoft asks.

Using the wrong account type can cause repeated login or verification failures.

24. Windows “Verify Your Identity” Notification

Windows itself may display a message asking you to verify your identity.

Check:

Settings → Accounts → Your info

and:

Settings → Accounts → Email & accounts

Look for messages indicating that the Microsoft account requires attention or verification.

Complete the verification using Microsoft's sign-in interface.

25. Passwordless Accounts

Some Microsoft accounts may use passwordless authentication.

Authentication may instead use:

• Microsoft Authenticator
• Passkey
• Windows Hello
• Security key

Therefore, not seeing a traditional password prompt does not necessarily indicate a problem.

26. VPN Can Trigger Additional Verification

A VPN can make a user appear to be connecting from a different IP address or geographic location.

For example, the user may physically be in India while the VPN exit node appears in another country.

Microsoft security systems may treat the sign-in differently.

If permitted, temporarily disconnect the VPN and retry authentication from the normal trusted network.

27. Remote Desktop and Cloud Servers

Microsoft accounts used through:

• Remote Desktop
• Windows Server
• Cloud desktops
• Virtual machines
• Hosted RDS environments

may encounter additional verification depending on security policy, IP reputation, device registration, or sign-in risk.

Business administrators should review the relevant sign-in information before repeatedly resetting user credentials.

28. Check Microsoft Entra Sign-In Logs

For Microsoft 365 organizational accounts, administrators can use Microsoft Entra sign-in logs to investigate authentication failures.

The logs can help identify:

• Sign-in status
• Failure reason
• Error code
• Application
• IP address
• Authentication requirement
• Conditional Access result
• Authentication details
• Device information
• Location information

This is often more useful than repeatedly changing passwords.

29. Conditional Access Policies

Organizations may configure Conditional Access policies requiring additional verification based on conditions such as:

• User
• Group
• Application
• Device
• Location
• Sign-in risk
• Device compliance
• Authentication strength

A user may therefore be able to sign in from one computer but not another.

Administrators should inspect the Conditional Access evaluation associated with the failed sign-in.

30. Security Defaults

Some Microsoft 365 tenants use Security Defaults.

These security protections can require users to register appropriate authentication methods and use MFA when required.

If verification suddenly becomes mandatory for several users, check whether tenant-wide security or authentication policies have recently changed.

31. Device Compliance

Organizations using Microsoft Intune or related device-management controls may require a device to be compliant before accessing corporate resources.

A device may be considered non-compliant because of issues such as:

• Required security configuration missing
• Device registration problem
• Policy not applied
• Compliance evaluation failure
• Unsupported device state

In such environments, identity verification alone may not resolve access.

32. Browser Extensions Can Interfere

Privacy, ad-blocking, cookie-management, script-blocking, or security extensions can sometimes interfere with authentication pages.

Temporarily test Microsoft login with extensions disabled or use an InPrivate/Incognito window.

If it works, enable extensions individually to identify the conflict.

33. Third-Party Antivirus or Web Protection

Security products may inspect HTTPS connections or filter authentication traffic.

If verification pages fail to load properly, investigate whether endpoint-security software is interfering.

On business systems, do not disable security software without authorization.

Instead, review logs, web-protection policies, SSL inspection, and vendor documentation.

34. Restart the Computer

A restart sounds simple, but it can clear temporary processes and refresh some authentication components.

After making account or authentication changes, restart Windows before concluding that the fix failed.

35. Check for Windows Updates

Install applicable Windows security and reliability updates.

Go to:

Settings → Windows Update

Check for updates, install approved updates, and restart the computer where required.

Outdated components can occasionally contribute to authentication problems.

36. Update Microsoft 365

For Office applications, check for Microsoft 365 updates.

Open an Office application and go to:

File → Account → Update Options

Then select:

Update Now

The exact options can differ depending on the Office installation and organizational update policy.

37. Repair Microsoft 365

If authentication problems are limited to Office desktop applications, Microsoft 365 repair can be considered.

Go to the Windows installed-apps area, locate Microsoft 365/Office, and choose the available modification or repair option.

Typically, Windows may offer:

Quick Repair

and:

Online Repair

Try the less disruptive repair option first.

Online Repair is more extensive and may require applications to be reconfigured or reactivated.

38. Create a New Outlook Profile

If the problem occurs only in classic Outlook and other authentication tests succeed, the Outlook profile may be damaged.

A new profile can be created through:

Control Panel → Mail → Show Profiles

Create a new profile and configure the account.

Do not delete the old profile until the new profile has been tested and all required data is confirmed.

This is especially important when local PST files or POP accounts are involved.

39. Microsoft Account Locked

Microsoft may restrict an account after suspicious or unusual activity.

Possible triggers include:

• Numerous failed password attempts
• Unusual geographic sign-in
• Automated login attempts
• Compromised credentials
• Suspicious account activity

Follow Microsoft's official account-recovery or security-verification procedure.

Avoid repeatedly trying passwords because additional failed attempts can complicate troubleshooting.

40. Verification Code Not Received

If Microsoft says it sent a code but you did not receive it:

Check:

• Mobile signal
• Correct phone number
• SMS blocking
• Spam/junk folder for email codes
• Alternate email accessibility
• Whether the code was sent to an old number
• Whether repeated requests have caused temporary throttling

Do not continuously request new codes in rapid succession.

41. Verification Code Says Incorrect or Expired

Verification codes are normally time-sensitive.

Always use the most recently requested code.

If you request several codes, an earlier code may no longer be valid.

Wait briefly, request a fresh code, and enter it carefully.

42. “I Don't Have Access to This Phone Number”

If the account displays an old number, first look for:

Sign in another way

If another registered authentication method exists, use it.

For organizational accounts, contact the administrator if no usable authentication method remains.

For personal accounts, use Microsoft's official account recovery and security-information procedures.

43. Avoid Repeated Password Resets

A verification problem does not automatically mean the password is wrong.

Repeatedly resetting the password can create additional problems because applications and devices may continue trying to authenticate using old credentials.

Before resetting the password, determine whether the failure is caused by:

• MFA
• Authenticator
• Conditional Access
• Browser session
• Cached credentials
• Device registration
• Security information
• Account lockout

44. Recommended Troubleshooting Order

For most users, follow this sequence:

1. Confirm Internet connectivity.
2. Verify Windows date, time and time zone.
3. Try signing in through a browser.
4. Try InPrivate/Incognito mode.
5. Confirm the correct Microsoft account is being used.
6. Complete the requested MFA verification.
7. Try another registered verification method.
8. Check Microsoft Authenticator.
9. Review account security information.
10. Restart the affected application.
11. Restart Windows.
12. Investigate relevant cached credentials.
13. Update Windows and Microsoft 365.
14. Repair the affected Office application if appropriate.
15. For business accounts, check Entra sign-in logs and policies.
16. Re-register authentication methods only when recovery options are available.
17. Rebuild application profiles only after less disruptive fixes fail.

This order helps avoid unnecessary changes.

45. Troubleshooting for Microsoft 365 Administrators

When a user reports repeated identity verification prompts, administrators should investigate before resetting everything.

Check:

• User account status
• Assigned licenses
• Authentication methods
• MFA registration
• Sign-in logs
• Authentication details
• Conditional Access
• Security Defaults
• Device status
• Device compliance
• Risk information, where available
• Recent password changes
• Suspicious sign-ins
• Account lockout
• Organizational authentication policies

The exact administrative options depend on the Microsoft 365/Entra licensing and configuration.

46. Security Warning: Never Approve Unexpected MFA Requests

A very important rule:

Never approve an Authenticator request that you did not initiate.

If unexpected MFA requests repeatedly appear, someone may know or be attempting to use your username/password.

Recommended actions include:

• Reject the request.
• Change the password through the official Microsoft service if compromise is suspected.
• Review recent sign-in activity.
• Inform the organization's IT administrator.
• Review authentication methods.
• Remove unauthorized methods or sessions where appropriate.

MFA should be treated as a security control, not as an annoying prompt that should automatically be approved.

47. Beware of Fake Microsoft Verification Pages

Cybercriminals frequently imitate Microsoft login and verification pages.

Before entering credentials:

• Check the website address carefully.
• Avoid login links received from suspicious emails.
• Do not provide verification codes to another person.
• Never approve unexpected Authenticator prompts.
• Be cautious when a caller asks for an MFA code.
• Use known Microsoft portals or trusted bookmarks whenever possible.

A verification code is effectively a security credential and should be protected.

48. When Should You Contact Your Microsoft 365 Administrator?

Contact your administrator when:

• MFA device is lost
• Registered phone number is unavailable
• Authentication methods cannot be changed
• Sign-in is blocked by organizational policy
• Conditional Access prevents login
• Device compliance fails
• Account is disabled
• User is stuck in an MFA registration loop
• Verification prompts affect multiple users
• Microsoft 365 applications repeatedly request authentication
• You suspect account compromise

Administrators have diagnostic information that normal users cannot access.

Frequently Asked Questions (FAQ)

1. Why does Microsoft keep saying “We need to verify your identity”?

Microsoft may need additional confirmation because of a new device, new location, password change, expired session, MFA requirement, security policy, unusual sign-in, or authentication-registration requirement.

2. Is “We need to verify your identity” a virus?

Not necessarily. It is a normal Microsoft security process when displayed through a genuine Microsoft sign-in interface. However, phishing websites can imitate Microsoft pages, so always verify the website and sign-in context.

3. Why am I asked to verify every time I sign in?

Possible causes include blocked cookies, corrupted browser sessions, expired tokens, account-policy requirements, VPN usage, device registration problems, or authentication configuration issues.

4. Why is Microsoft Authenticator not sending notifications?

Possible causes include disabled notifications, network problems, an outdated registration, battery restrictions, a changed phone, or an account configuration issue.

5. Can I verify without Microsoft Authenticator?

Possibly. It depends on which authentication methods are registered and which methods the organization's policy permits.

6. What if I lost my Authenticator phone?

Try another registered authentication method. For a business account, contact your Microsoft 365 administrator if no alternative method is available.

7. Can an administrator reset MFA?

Administrators with appropriate permissions can manage authentication-related settings and may be able to require a user to re-register authentication methods, depending on the tenant configuration and policies.

8. Why does Outlook repeatedly ask me to verify?

The cause may be cached credentials, expired authentication tokens, a password change, Office activation, Outlook profile problems, MFA, or organizational security policies.

9. Should I delete everything from Credential Manager?

No. Remove only relevant entries when you understand what they are associated with. Deleting unrelated credentials can affect other applications and network resources.

10. Does changing the password fix verification problems?

Sometimes, but not always. MFA, Conditional Access, authentication-method registration, device compliance, and browser-session problems may remain even after a password change.

11. Can a VPN cause Microsoft verification prompts?

Yes. A VPN can change the apparent IP address and location of the connection, which may contribute to additional security verification.

12. Can incorrect Windows time cause sign-in problems?

Yes. Incorrect date, time, or time-zone settings can interfere with secure authentication and token validation.

13. What does “More information required” mean?

For organizational accounts, it commonly means the user must register additional security or authentication information required by the organization.

14. Is it safe to approve every Authenticator notification?

No. Approve only requests that correspond to a sign-in you personally initiated.

15. Why does Microsoft ask for number matching?

Number matching helps protect against accidental approval and MFA push-notification attacks by requiring interaction with the sign-in session.

16. Why can I sign in through a browser but not Outlook?

This usually indicates that the account itself is functioning and the problem is more likely related to Outlook, Office authentication, cached credentials, or the local Windows environment.

17. Will reinstalling Office fix the problem?

It may help in certain cases, but reinstalling Office should not be the first troubleshooting step. First check the account, MFA, browser login, credentials, updates, and repair options.

18. Can Conditional Access cause verification requests?

Yes. Organizations can configure Conditional Access policies that require MFA or other controls depending on user, device, application, location, risk, and other conditions.

19. What should I do if I receive an unexpected verification request?

Reject it. Review your account security and recent sign-ins, and change your password if unauthorized access is suspected.

20. How can an administrator find the exact reason for a failed Microsoft 365 sign-in?

Microsoft Entra sign-in logs are one of the most useful places to investigate. They can show the sign-in result, authentication requirements, Conditional Access evaluation, application, device, and related diagnostic information.

Conclusion

The Microsoft “We Need to Verify Your Identity” message is usually a security feature rather than a Windows or Microsoft 365 malfunction.

The most important step is to determine where the verification is failing.

For individual users, start with Internet connectivity, system time, browser sign-in, Microsoft Authenticator, registered security information, cookies, and cached credentials.

For Microsoft 365 business environments, administrators should additionally investigate Microsoft Entra sign-in logs, authentication methods, MFA configuration, Conditional Access, Security Defaults, device registration, and compliance policies.

Avoid immediately deleting profiles, removing accounts, resetting MFA, or reinstalling Microsoft 365. Start with the least disruptive checks and progress toward advanced troubleshooting only when necessary.

Most importantly, never approve an unexpected Microsoft Authenticator request or provide an MFA verification code to another person.
