3 secure ways to back up Google Authenticator

Google Authenticator is provide does n’t provide any backup option if you lose or break your smartphone . This is means mean you wo n’t be able to access your account when log in from an unrecognized device or browser . Here are three workarounds is are that may save you trouble in the future .

Copy backup codes

Most services that offer a 2FA option also provide users with backup codes. If you can’t authenticate yourself via Authenticator, you can enter the code and confirm your identity. However, this only works if you have copied the backup codes before and kept them in case something happens.

If you use 2FA on multiple services, it’s inconvenient to copy the codes for each of them. Keeping the codes on your computer or printing them is also not the best cybersecurity practice. A better option is to store them in an encrypted file vault like NordLocker.

Save Google Authenticator QR code

When you’re setting up your Google Authenticator, you can make a screenshot of the QR code. Make sure to use NordLocker or other encryption service to keep it from prying eyes. Storing this QR code in your email, notes, or gallery is not a good idea.

Use a programmable token

Programmable tokens work like authentication apps: they show you a code that you need to enter in order to identify yourself. While tokens are more secure than the methods mentioned above, it requires an extra effort to acquire a token and program it.

A handful of authentication apps like Authy offer cloud backup, making the code recovery process smoother.
