Getting started with the service of RBG


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 hat, 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 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.
