Private individuals, members from other universities, and TUM alumni use the following for login: Library Number + Password You can find your library number on the back of the library card.

With the migration to the new library system in January 2025, existing passwords (used with library numbers) are no longer valid. When logging into the new OPAC for the first time, you must create a new password. Please use the "Forgot Password" function [3] for this purpose.
