Changing of Password and Shell

Please always use the web interface on the LRZ server to change your login password or your login shell for the cluster systems. Cluster-local commands cannot be used for this purpose.Passwords must be changed at least once  in 6 months. We are aware that this measure imposes some overhead on users, but believe that it is necessary on security reasons, having implemented it based on guidelines of BSI (federal

agency for information security) and the IT security standard ISO/IEC 27001. You are able to determine the actual invalidation date for your password by logging into the above-linked web interface and selecting the menu item "Person -> view" or  "Account -> view authorizations". In order to prevent being surprised by a password becoming invalid, you will be notified of the need to change your password via e-mail. Even if you miss the deadline for the password update, this only implies a temporary suspension of your  account - you will still be able to log in to the ID portal and make the password change.Please note the LRZ policy for the selection and use of passwords:

Changing the password is also necessary after it has been newly issued, or reset to a starting value by a master user or LRZ staff.  This This assures that actual authentication is done with a password known only to the account owner.
