A profile is a group of persons of TUM, which you are assigned to.
There are different profiles at TUM: applicant, student, employee, alumni. A profile provides you with specific applications and rights.
You can be assigned to more than one profile, for example if you were student at TUM before and now you study again. In this case you have the profile "Alumni" and "Students". You can change your profile in TUMonline via the head symbol at the top right. (instructions)
