Welcome to the web site of the systems-support group of the Department of Computing Science
These pages contain descriptions of the departmental computer systems, as well as information regarding their use.
They are intended to be an information resource for all who use the computer systems of the department; faculty, staff, and students inclusive.
The contents of these pages are maintained by the computer-systems support group; that is, those who are responsible for the acquisition, installation, and maintenance of both the hardware and the software of the department.
The members of the computer-systems support group work together to create quality, functional computer systems. These systems are for you, the computer user, and to meet your needs requires cooperation. If you discover something which does not appear to function correctly, or behaves strangely, please inform someone in the support group, as they are there to help you.
Changes Summer 2026
Mail change as of 2026-06-29
The use of Service Password is now enforced, except for accounts/people who have recently (2026-06-14 - 2026-06-28) used Account Password to login to the mailserver.
This forces new mail client setups to use Service Password, but without suddenly breaking the mail clients for existing/active users during the summer vacation.
Note: Everyone SHOULD replace their Account Password logins with new Service Passwords
To help you identify if you have any mail clients that needs to switch to ServicePassword authentication,
you can see a list of your recent mail server logins on the Mail ServicePassword Usage page.
Planned changes as of summer 2026
MFA enrollment will be forced on the CS-account
Mailserver will require Service Passwords, the regular account password will not work
- The regular CS-account password will no longer be accepted by the mailserver
- Your mail client (Outlook, Thunderbird, Apple Mail, ..) will likely give an error and prompt you for a new password
- (Webmail is unaffected)
- Create and Manage Service-Passwords at https://webapps.cs.umu.se/password/service/ and use the generated password instead of your regular account password
To help you identify if you have any mail clients that needs to switch to ServicePassword authentication,
you can see a list of your recent mail server logins on the Mail ServicePassword Usage page.
