Remove App Passwords
If you lose a device or stop using an app that was authorized with an App Password, we recommend revoking its App Password so that no one can access your Google Account from that device.
App passwords allow apps or devices that don’t support 2-Step Verification codes to access your Google Account. If you use 2-Step Verification and accessed your Google Account from an app or device like Gmail on your iPhone or iPad, you probably used an App Password.
Note: If you have the latest operating system on your iPhone, iPad, or Mac, you will no longer have to use App passwords to use 2-Step Verification.
To remove an App Password:
- Visit your App Passwords page.
- You'll see a list of the apps you've created App Passwords for.
- Next to the app you want to remove access from, click Remove .
If you're an Android 4.0+ user, we recommend removing "Android" from the Apps with access to your account.
Once revoked, that App Password can't be used to access your Google Account again. If you want to start using your account on an app or device again, you'll need to generate a new App Password.
