Matrix card authentication

Matrix cards (also called "grid cards") are used as a second factor to authenticate users. A user has a list of codes - typically printed on paper - that are requested to be entered in the authentication process.

Airlock IAM offers the following services for matrix cards:

The following types of matrix cards are supported:

  • Matrix card (a¬†grid card with codes organized in a coordinate system):

  • Indexed TAN-list (an indexed sequence of codes, so every code has an associated index):

Note that the "TAN list" mode without indices will be removed in future versions of Airlock IAM. It has serious security draw-backs and has therefore be deprecated.

How authentication with matrix cards works

  • During the authentication process the user is required to enter one or more matrix codes.
  • Depending on the configuration, it is either a coordinate (matrix card) or an index (indexed TAN-list).
  • The user then enters the code which he is able to retrieve from the printed list of matrix codes that was sent to him.
  • After entering the correct matrix code(s), the user is authenticated successfully.
