Employees

If you as an employee do not have a u:card or a digital signature (mobile phone signature/ID Austria), the only option available to you is Digitale Unterschrift von Kollege*Kollegin (Digital signature of colleague). Contact your manager if you do not know of a colleague with a digital signature (mobile phone signature/ID Austria).

Identity verification via video telephony, as offered to students, is not possible for employees.

Students

If you as a student do not have a u:card or a digital signature (mobile phone signature/ID Austria), you can use the identity check by the Teaching Affairs and Study Services service unit. Note that this option takes significantly longer than the other methods and only choose it if it is absolutely necessary.

u:card

After you have created a ticket using the Servicedesk form Zweiten Faktor ändern (Changing second factor, in German), you have 4 hours to validate your u:card at a u:card terminal.

After successful validation, the following applies:

  • VPN: Your request will be processed by a ZID employee (on weekdays). Please allow for corresponding waiting times. You will receive a message as soon as you can change the second factor.
  • Microsoft 365: Your second factors will be automatically deleted within 20 minutes. You will be prompted to set up a second factor the next time you log in to Microsoft 365. Set this up as soon as possible to ensure the security of your Microsoft 365 account.
