Google: Using Google 2-Step backup codes

If you lose your phone or otherwise can't get codes via text, voice call, or Google Authenticator, you can use backup codes to sign in. If you don't have your security key, you can also use these codes to sign in.

Once a backup code is used to sign in, it becomes inactive.
Generating a new set of 10 codes can be done whenever needed. Once a new set is created, the old set will automatically become inactive.

Please store your codes wherever you keep your other valuable items. Like the codes on your phone, backup codes are only valuable to someone if they manage to also steal your password.

Signing in with a backup code

Locate your backup codes or contact the School of Business Help Desk to obtain a backup code.
Sign into Gmail or another Google service.
Enter your WFU email and password.
When asked for your verification code, click More options or Try another way.
Select Enter one of your 8-digit backup codes.
Enter your backup code.

Optional: As each code can be used only once, it is helpful to mark the code as used.

Create and view a set of backup codes

Click your Google Profile picture, and click Manage your Google Account.
On left navigation menu, select Security & sign in.
Scroll to the How to sign in to Google section, and select Backup Codes.
Sign in to your WFU Google Account and select to Print Codes or Download codes.

If you think your backup codes were stolen or if you're running out, select Get new codes. Your old set of backup codes will automatically become inactive.

Can't find the backup codes you downloaded? Search your computer for "Backup-codes-username.txt" with your username. For example, if your username is google123, search for "Backup-codes-google123.txt."
