Changing the Password

It can only be reached within the DESY-Intranet via the Registry Webinterface.

Password Aging

It is necessary to change the password for every account at least every 6 months (180 days). Therefore every night a cron job is checking the age of all passwords and sends an e-mail to those users whose password age reached certain limits.
If a user doesn't change the password before expiring date, we lock the account for security reasons. The user gets this message several times before the expiring date.
If a user has gotten a new account or if his password was reset by the system administrator the user needs to change this first password within 5 days. We recommend, though, to do this immediately.
If an account was locked the user needs to contact UCO.
