Enabling two-factor authentication (2-FA) keeps your Gmail account secure. The Gmail two-factor authentication adds an extra layer of security by requiring that for persons to access a Gmail account, they must have a password and a specific security key. To do this, Google sends a verification code that is unique to your account through a voice call, the Google authentication app, or via text.REVOKE AN APPLICATION PASSWORD FOR GMAIL

The verification codes generated by the two-factor authentication process do not work with some apps and devices. When this occurs, one has to generate an app-specific password for the app or device to authorize it to “access mail and folders through IMAP” or mail through POP.

You can revoke the password when you no longer use the app or device or no longer trust it to keep the password secure.

Revoking one app-specific password does not affect other passwords you generated for different applications or devices.


To delete an application-specific password generated to access your Gmail account through IMAP or POP, the following is very handy:

  1. Go to your name or avatar and select Google Account
  2. Go to the security tab and select App passwords
  3. When prompted, enter your Gmail password
  4. In the App password screen, choose an App Password and select Revoke
  5. If you do not see “My App Passwords”, it means you are not currently using any password. You can add new passwords on the same screen.
