Science login

Every employee or student of the Science faculty receives a personal Science login. This allows you to use services such as Eduroam, storage, VPN, computer lab PCs, JupyterHub and GitLab.

A Science login usually resembles your name and does not contain periods, capital letters or an at sign (@). For example johndoe.


All settings related to your Science login, like setting your password and managing groups, mail aliases, mail forwarding and vacation message can be managed in DIY.


After registration, students automatically receive a login based on the information from Osiris. Once the Science login is created you will receive an email with further instructions. This email is being sent to the email address registered in Osiris.

The email address that comes with your Science login ends with Email sent to that address will be automatically forwarded to your address. This can be adjusted on DIY.


If you want to keep the Science login while you are no longer studying here, C&CZ will only do this on request from the contact person of your study programme. Inquiries should be directed to the [Student Information Point (STIP)] ( of the Education Centre.

Employees, guests and trainees

New employees, trainees and guests receive a Science login at the request of the contact person of the department. A Science login usually includes an email address that ends with Incoming email can be read from our email facility, or can be forwarded via DIY to, for example, the address. For interns who are also students here, it is not necessary to request a Science login.
