When you use an authenticator app, the multifactor codes are available in-app instead of through a text. Want to make the switch from a 2FA process ruled by SMS messages to a more secure option?

How to Add an Account to Google Authenticator You need two things: Google's authenticator app and a code from the account you want to add to the app (Facebook, Amazon, your bank, etc.).

Google Authenticator will now sync your 2FA codes to use on different devices The cloud-based syncing means you can access the two-factor authenticator codes from any device.
