How Authenticator App Works on Android

When you sign up or login into your online account protected by 2FA, first, you enter your username and password (something that you know). Then you need to enter the TOTP generated by the Authenticator app (something that you have). When you log in, the authenticator and the service perform a real-time crypto operation. If the results are the same, the secret key will be identical, and you’ll be successfully authorized. If you have more questions about how the app works check out our FAQ section.
