A recovery email is an additional email address that you list in your account settings, often in security settings. It is used when you are unable to sign in normally to "recover" access by setting a new password. A recovery email address helps you get back into your account and is where Google sends you security notifications. It is also used to regain access to an account youre unable to sign in to. If you forget your password, someone else is using your account, or youre locked out of your account for another reason, you can use your recovery email to reset your password.

To set up a recovery email address for your Google account, you can follow these steps:

1. Open your devices Settings app and tap Google and then Manage your Google Account.
2. At the top, tap Security.
3. Under "Ways we can verify its you," tap Recovery email.
4. You might need to sign in.
5. From here, you can add a recovery email, change or delete your recovery email. Follow the steps on the screen.

When setting up a recovery email address, it is important to choose an email address that you use regularly and is different from the one you use to sign in to your Google account. It is also recommended that your recovery email address should be on a different email service.
