Multifactor-authentication (MFA) is a procedure in which users have to confirm their login via a separate medium/device (token).

This increases security and can protect users from data misuse in cases where their login data is lost or compromised.

RWTH Single Sign-On supports two-factor authentication as MFA. The second factor is implemented via tokens.

All service providers (Webservices using RWTH Single Sign-On) decide independently whether or not a second factor is required to log in to their service.

As per usual, the single sign-on login is valid for an entire browser session and across all services accessed during that session.

Login using MFA

After logging in via RWTH Single Sign-On, you can choose a token as the second factor.

You must have created the corresponding tokens in advance.
