Student Accounts for other subgroups

Apply for a new account

If you want to apply for a CS-Account as a guest, informatics minor or a participant of FFF-Programme, you have to take following prerequisites into consideration:

  • You must have a valid certification by your lecturer/mentor. You will need them to sign your application.

To request creation of your account, please go to one of the account terminal (in the b-it entrance hall or in 0.014) or call the account web page. There select apply here, and on the next page your status.

Enter your data, read the usage agreement, und and select create account.

You'll now receive an e-mail with a confirmation link (please select that) and a PDF, please print it, sign it (twice!) and let your lecturer co-sign it.

You can submit the signed document either:

  • Currently scanned (200-300dpi suffice as e-mail to
  • GSG office, room 0.014 in the Informatics building
  • as paper mail.

Our staff will enable the account if all inputs where acceptable. If successful, you'll get an automatic e-mail.

Now your account is enabled, and you can create your password on the password reset page.

Extend your existing account

If you already have an CS account that nears its expiration, you'll have to create a renewal request online (only from the Informatics/b-it network) , sign it and send it to us. If you're not in the Informatics or b-it building, you can reach that link through a VPN or a SSH tunnel.Currently also reachable online from outside!

Please consider these points:

  • You'll have to enter the password corresponding to your account.
  • You must have a valid endorsement by your lecturer/mentor. They will have to sign your application.

Please log in with the requested credentials. Then you'll have to check and maybe update your personal data. Please keep in mind that you'll have to use your Uni-ID as e-mail address.

Your account is not yet renewed. (Download and) print the request and submit it after signing in one of these ways:

  • Currently: scanned (200-300 dpi are enough!) as e-mail to
  • Preferably: GSG letter box (lecture hall building, locker room behind the janitors' office) or as letter
  • In case of questions: GSG helpdesk room 0.014 in the Informatics building

Our staff will enable the account if all inputs where acceptable. If successful, you'll get an automatic e-mail.


Where are the Account Terminals?​

One account terminal is in the b-it entrance hall. But you also can create your account creation of renewal request online.

"My Enrollment Number is not in the system"

Historic message when the system didn't believe you study Informatics etc. See next paragraph.

"According to our records you do not study Informatics etc."

This is usually the case when you were not yet enrolled while we got the list of the students. Please send us a verifiable enrollment certificate (PDF) via e-mail. You can create that yourself quickly on BASIS. The procedure is explained here.

RWTH Students (B-IT Media Informatics students): please send us your RWTH enrollment certificate instead (download in RWTHonline → Documents; after enrollment at RWTH).

"When do I have to renew my account?"

The CS or b-it identifier must be extended by 30 November of each year. The extension period is the beginning of the winter semester until the 30th of November of the same year. Please renew your account within the regular extension periods!

"My Account has expired"

If it was not possible for you to renew your account in due time, please send us an e-mail with your eletronic enrollment certificate. This procedure also applies for students who forgot to extend their accounts at the beginning of the semester.

"I forgot my password"

Please use the password reset page.

"I forgot my account name"

Please use the password reset page (2nd option). If you still remember the password, you don't need to actually change the password after you've been reminded of the login name.

"My Uni-ID isn't registered with my account, so the password reset does not work"

Please send us an e-mail with your eletronic enrollment certificate from your Uni-ID e-mail. If all fits, we'll change your registered E-mail address to your Uni-ID.

"I lost my paper application"

For a renewal request, simply download a new one from the application server. For a new account, send us an electronic enrollment certificate as e-mail.

"The password is too easy"

To construct a password for a computer science / b-it identifier, the following criteria must be met:

  • password must contain a minimal of 12 characters
  • first 8 characters must contain:
    1. Latin uppercase letters : A, B, C, … Z
    2. Latin lowercase letters : a, b, c, … z

  • The character categories should appear mixed (not as in “1Hello2”).

A little tip: think of a word and modify it: Example: Bleistift (engl. Pencil) → B1ejsT.ft (“k” becomes “1”, “i” becomes “j” and “.”)
