How to enable 2-step verification
Your Gmail account is non-compliant, as it’s protected by a two-tier password. 2-step verification is a powerful general security feature of Gmail and Google.
Enabling 2-step verification will send a message with a confirmation code to the phone number you registered for 2-step verification each time you log in to Gmail. Without this code, you will not be able to log in to Gmail. Activating 2-step verification is very likely to lose your Gmail account.
Note: Enabling 2-step verification for your Gmail account will also enable 2-step verification for all other Google products, including Google Plus, Google Maps, and YouTube.
