Airlock IAM supports many different token types (MTAN, OTP, CrontoSign, Matrixcards, etc.). Token types can be mixed, i.e. be used at the same time, in different ways.
This page lists the different ways to mix authentication token types.
Most of the listed auth method selection methods are applicable forĀ second authentication steps, because the user has to be known.
Some of them are ready to work with the "Main Authenticator", others are not. If using a selection method not compatible with the "Main Authenticator", use the "Meta Authenticator" plugin instead.
