About two-step verification
Two-step verification is an optional feature that adds more security to your WhatsApp account. You’ll see the two-step verification screen after you successfully register your phone number on WhatsApp. You can learn how to enable two-step verification in the article.
When you enable two-step verification, you have the option to enter your email address. This allows WhatsApp to email you a reset link in case you ever forget your PIN, and also helps safeguard your account.
To help you remember your PIN, WhatsApp will prompt you to periodically enter your PIN. Unfortunately, there isn’t an option to disable this without disabling the two-step verification feature. Learn more about managing two-step verification settings in this article.
Note: 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 registration in this article.
