How do TOTPs work?

Whether you're using a password manager with a built-in two-factor authenticator or a dedicated authenticator app, TOTPs work the same way: When you set up 2FA, a secret key is created and shared between your authenticator app and the service you're logging into. Then, every time you log in, the following process happens in just a few seconds.

Step 1

You log into a service you've set up with 2FA and you're prompted for a code generated by your authenticator app.

Step 2

You open your authenticator app and generate a unique code for the service you're logging into. The service generates a code matching the secret one it shares with your authenticator.

Step 3

You return to the service and enter the code. The service checks that the code you've entered is correct, and then you can log in securely.

What are the benefits of TOTPs?

TOTPs create an extra layer of security for your online accounts without complicating the log-in process. They're an excellent alternative to traditional passwords for several reasons:

Easy to use

Logging in with a TOTP is even easier than using a password. There's nothing to memorize, just enter the code and log in.

Easy to protect

Just like your passwords, TOTPs can be safely stored and quickly accessed via your password manager or your authenticator app.

More secure than passwords

Because they're time-sensitive and generated between your device and the service you're using, TOTPs are much harder for cybercriminals to intercept than traditional passwords.

Accessible anywhere

You can use TOTPs on your phone, your tablet, or your laptop, and you can use them on any platform. Backups of your codes can be created for security or to use your TOTPs across multiples devices.
