About registration and two-step verification

When you create a WhatsApp account, you’ll see two different screens:
  • Registration: This screen appears when you're creating a new account or re-registering your existing account. To confirm that you own the phone number, you’ll be prompted to enter a 6-digit registration code sent to you via SMS or phone call.
    • Note: You can get a registration code through email if you are re-registering and have previously set up two-step verification with an email address.
    Verifying your phone number with a registration code is the only way you can activate your account, and you must be able to receive the code on your phone. Learn how to register your phone number in this article.
  • Two-step verification: This screen appears after you successfully register your phone number on WhatsApp. Two-step verification (2FA) is an optional feature that adds more security to your WhatsApp account. When enabling this feature, you create and confirm a unique PIN that’s required to access your account. The two-step verification PIN is different from the 6-digit registration code you receive via SMS or phone call. You can learn more about two-step verification in this article.
Remember: Never share your 6-digit registration code or two-step verification PIN with anyone.
If you didn't enable two-step verification, but are prompted to enter a PIN, the previous owner of the phone number might have enabled it. In this case, you'll need to wait 7 days before resetting the PIN to access your account.
If you forgot your PIN and you've successfully registered your phone number on WhatsApp, tap Forgot PIN? to create a new one. You can manage your two-step verification PIN settings at any time by going to your WhatsApp settings > Account > Two-Step Verification.
Note: WhatsApp can only be used with one phone number at a time. After you successfully register your phone number on WhatsApp, anyone who might be using your account is automatically logged out and your account is protected.
Note: In some cases, WhatsApp can automatically verify your phone number. Find out more.
