One identifier means an account supported by a different organization of the TU Munich and with which you could gain the access to the IT-Infrastructure that they've supported. The identifiers are often named as Login or user-id on different websites.

It is important to remind that different identifiers have nothing to do with each other (and in most cases, they have or should have different passwords).

The FMI identifier

the FMI identifier also knew as a Mathematic/Informatic identifier, RBG Identifier, or ma/in.tum identifier.

This identifier consists of the first eight letters of your surname or eventually some more letters from your first name. Ms. Mareike Musterfrau has, for example, the identifier 'musterfr' and her younger sister Xanthippe Musterfrau has for example 'musterfx' while the identifier has to be identifiable for each user. With this account, Ms. X Musterfrau can log in to the computer under Linux OS in the computer hall (Rechnerhalle), however this identifier and the password don't work for Windows OS, please see the texts below.

The FMI identifier will be given to you since the starts your study here from the Infopoint of Mathematic or Informatic. The employees receive the FMI-identifier from the chair administrators (Lehrstuhladmin) which are assigned by the RBG.

The MyTUM identifier

The MyTUM identifier is used, for example, to log in to the website: When you are logged in to the page and click on 'your E-mail address', you will see a cryptical address with two letters 2 numbers and three letters (e.g. under the E-Mail address with your name on it (e.g.

The cryptical part before the '@' character is your LRZ identifier and the password for this LRZ identifier is the same as the MyTUM identifier.

The Windows identifier

This identifier is used to log in to the Windows-computer on the faculty of informatics. If you do not want to use the Windows OS you could then for sure ignore the Windows identifier. If you want to use the Windows OS you have to set a password for it. Go to the website of and set a password there. The username is here your in.tum Identifier.

Eduroam WIFI and LAN connection in computer hall (Rechnerhalle)

To set up the Eduroam WIFI is slightly different depending on the operating system and device (however no matter what Operation System, you will need here the LRZ identifier that mentioned above). The LRZ gives a short manual about how to set up the LRZ WIFI:

Eduroam also provides the interface to connect in our Computer halls using a cable. The RBG-Helpdesk lends cables against your student ID as a deposit in room 00.07.036. Short instruction for the connection is listed here:


You need the Identifier to print in the faculty of mathematics and informatics. Students can buy print contingent from the 'Fachschaft' (Room 00.06.036).

Notice on data protection in computer halls

When you are working with a Linux computer in a computer hall, please pay attention to the data that you saved on the computer. The default setting for access rights is that no other users (including fellow students) can view your files. You can manually change this (and also find out how this goes) yourselves. But then pay attention that you do not be too lenient with the access rights!
