What is Google Authenticator?
What is Google Authenticator?
Google Authenticator is a two-factor authentication (2FA) app that allows you to add an extra layer of security when logging into various online accounts.
When you link the app to your accounts (like Facebook, Instagram, email, etc.), Google Authenticator will generate a timed and unique verification code each time you log in. You’ll then input this code on the app or site you’re logging into.
Common reasons for not being able to access Google Authenticator
As long as you have your device with Google Authenticator on it, you should be able to access the codes you need.
Here are some reasons you may not be able to access Google Authenticator:
- You lost your phone
- Your phone was damaged (i.e., water damage, dropped, died, and won’t turn on).
Not having access to any of your mobile apps may be a sign of a bigger issue — ID theft. You can avoid this by simply securing your mobile data. Will Clario, you will always be notified of any data breaches so you can react quickly and restore safety.

Erase your lost phone remotely
By erasing the data and apps from your lost phone remotely, you can prevent someone else from accessing your Google Authenticator app — therefore, protecting any accounts that it is linked to.
The instructions for erasing your phone’s data remotely will vary depending on your device. But here are the most common ways to do this for iPhone and Android devices.
How to erase iPhone data remotely:
- Go to iCloud.com and sign in
- Tap your profile icon in the upper right corner
- Hit iCloud Settings > Find devices
- Select the device you want to erase
- Click Erase iPhone
- Confirm and enter your Apple ID password when prompted — you may also need to enter a verification code or answer security questions if you’re not using a trusted device
- If you’re asked to enter a phone number or message, indicate your device is lost and provide another contact method.
How to erase Android data remotely:
- Go to google.com/android/find
- Click on the device that you want to erase
- Click Erase device and follow the on-screen prompts.

Backup codes
If your Google Authenticator key is lost, backup codes can help you access accounts that Google Authenticator is linked to. Many online services provide one-time backup codes in case of emergencies. If your account provides an emergency backup code, use that to log in.
SMS code
Some services offer alternative methods for logging into your account, like sending a code via SMS or text message. If you can’t access Google Authenticator, try an alternative solution like this.
Verification on another device
If you have another device — like a Google Home Mini, tablet, or laptop — that is still logged into the account you wish to access, you can go to your security settings and disable or remove 2FA from that account.
Contact customer service
Suppose you can’t authenticate yourself on the personal accounts you are trying to access and don’t have access to Google Authenticator. In that case, you’ll likely need to contact customer service for that account. Customer service can help remove 2FA or reset your password and settings from their end.
