WhatsApp Business has become one of the most important communication tools for businesses worldwide. It contains customer conversations, invoices, payment details, business catalogs, marketing campaigns, and confidential customer information.

Unfortunately, WhatsApp accounts are frequent targets of hackers through:

• SIM swap attacks
• Social engineering
• OTP theft
• Phishing attacks
• Malware
• Fake support scams

To improve account security, WhatsApp Business provides Two-Step Verification, an additional security layer that requires a 6-digit PIN whenever your phone number is registered again.

Without this PIN, even if someone steals your SIM card or receives your SMS verification code, they still cannot activate your WhatsApp Business account.

This guide explains everything you need to know.

What is Two-Step Verification?

Two-Step Verification is an optional security feature that adds a custom 6-digit PIN to your WhatsApp Business account.

Whenever someone attempts to register your phone number on another device, WhatsApp asks for:

1. SMS Verification Code
2. Six-digit PIN

Without both, account activation fails.
