ProxyIdP offers a more secure way of authentication on top of passwords – the so-called Multi-Factor Authentication (MFA). Once activated, an additional form of authentication is required in addition to the required password, for example in the form of a verification code. This function makes it more difficult for potential attackers to misuse someone else’s account.

Multi-Factor Authentication as described here applies only to services that use ProxyIdP.

About ProxyIdP Multi-Factor Authentication

Info

Within ProxyIdP MFA, the verification code method (TOTP) must be set first.
Subsequently, a security key (WebAuthn) can be used together with the verification codes.

titleGlossary

Multi-factor authentication

Identity verification using two or more authentication factors (e.g. something I know + something I have).

Security key

Usually a physical or a virtual device used for identity verification based on a secret key.

Verification codes

One-time codes with limited time validity, generated by an authentication app, e.g. Aegis.

Recovery codes

One-time codes which can be generated during initial setup and saved or printed. They can be used to authenticate in case of losing all other authentication devices.

Tokens

Means of authentication other than a password or a PIN, including security keys, verification codes and recovery codes.

Verification codes (TOTP)

Before setting up Multi-Factor Authentication using authentication codes, you need to have a mobile app that generates the codes. We recommend using Aegis Authenticator for Android and Raivo OTP for iOS, also you can check the List of verified TOTP applications and password managers. You then need to add a token for the authentication codes in the ProxyIdP Multi-Factor Authentication settings and link them together.

Security keys (WebAuthn)

Security keys offer maximum levels of security, it authenticates the device using so-called "asymmetric cryptography". A computer or smartphone can be used as a security key if it supports this function. When logging in, depending on the type of your device you need to either confirm a notification, use your fingerprint or facial recognition.

...

Adding the first token automatically sets up Multi-Factor Authentication for all IT services under MUNI Unified Login. Managing for which services multi-factor authentication is enabled is possible in the User Profile.

Backup codes for restoring access

As a part of the initial set up of Multi-Factor Authentication, a set of backup codes is generated. These are used in case all registered devices are lost and access has to be restored. The codes can be saved in PDF or printed out.
