To the account application


The login is always the same for all services. It is typically generated from the first letter of the first name and the complete surname. For example, Joe User receives the login juser.


You are provided with three passwords for an account. The first is required for logging in, a separate password is valid for e-mails and the third is for access to our network. The following table provides an overview.

Designation Explanation
Login Log in to the computer workstations in the GZI or Services
E-Mail E-mail account for the TechFak.Uni.Bielefeld.DE domain
Network Log in to the network, WiFi, LAN, or VPN

For a new account, we set the login and mail password to the same. Please change the password as soon as possible on a system managed by us, e.g. in a computer pool room (see Workstations) or on (see Remote access). We recommend using different passwords so that passwords cannot be changed if a password is lost.

On our centrally managed systems, these passwords can be changed on the command line or in the terminal with tfpasswd login and tfpasswd mail, respectively.

The network password cannot be set by yourself. Instead, the password can be displayed with tfpasswd net. Your current mail password is required for this.

E-mail address

You will receive an e-mail address for each account.This address is made up of your login and the domain, e.g. To retrieve the e-mails you can either use our webmailer or set up the address in your e-mail client. You can find the settings in the following table:

Input Comment
