+Multi-Factor Authentication (MFA)
+=================================
+
+The Executive Board of ETH has decided to introduce multi-factor authentication (MFA)
+across the board at ETH Zurich in the second half of 2022.
+
+Affected services and set-up instructions
+-----------------------------------------
+
+For a list of affected services and set-up instructions,
+please refer to the official article (
+[de](https://unlimited.ethz.ch/x/TxmJBQ) or
+[en](https://unlimited.ethz.ch/x/WwZaBg))
+in the [ETH IT Knowledge Base](https://unlimited.ethz.ch/display/itkb/).
+
+Alternative software
