You may know this method by many alternative names, including “code from verification app”, “verification code”, “authentication code”, “code from authentication app”, “6 digit code from code generator”, “code from Google Authenticator” or “verification code from the Google Authenticator app”.

The advantage of this method is its versatility - you can copy the one time code from the app in your smartphone to another app, type it on your PC or even a smart TV. The only requirement that the device you want to authenticate on needs to fulfil is the capability to enter digits.

You can use any TOTP app, for example one of those listed below. Alternatively you can use the TOTP capability of your password manager (e.g. BitWarden or LastPass Authenticator). If you already have a TOTP app installed, you do not have to install another one, you can just add MUNI Unified Login.

You may know this method by different names, including “FIDO2”, “U2F”, “security key verification”, “universal second factor” or simply “security key”.

The advantage of this method is its simplicity - you do not need to grab your smartphone, open an app and type in a code, you just confirm the authentication e.g. by pressing a button or using your thumb for fingerprint. You may register various devices and use a different method of authentication in each one depending on the device’s capabilities.

In order to use WebAuthn, you need to use one of the supported web browsers together with the operating system capability, an app or a physical authenticator (e.g. a YubiKey).

All web browsers officially supported by MUNI Unified Login support WebAuthn authentication.
