🔐 Problems with two-factor authentication (2FA)
-
You have enabled 2FA. When logging in, a code is requested by email, but it does not work.
-
A: The code does not arrive
-
- Check your spam folder.
- Use the "Resend email" button. A new code can be requested every 60 seconds.
- Didn't receive an email?
-
B: The code has expired or was entered incorrectly too many times
-
- Each code is valid for 10 minutes. Simply request a new code.
-
C: No longer have access to the email inbox
-
- If your school uses Single Sign-On (e.g. IServ, VIDIS, Moin), log in through it. SSO login works without a code. Then disable 2FA under My Account and enable it again with a current email address.
- Without SSO access, contact us via the contact page. Provide your username and server.
-
Tip: For 2FA, use a private email address that you can access permanently, not your school email address.
