2 Problems with Login/2-Factor-Authentication

Q: I have lost my 2FA device or can no longer generate One-Time Passwords using my software token.

3 Deregistration

If you are no longer using the bwUniCluster 2.0 and want to deregister yourself, please follow the Deregistration instructions. This will also automatically remove your e-mail address from the user mailing list and you will no longer receive user announcements for this system.
