If Technische Universität München had your data

Look for Technische Universität München’s own notice or letter: it should say what of yours was involved. Keep it.
Change your Technische Universität München password, and the same password anywhere else you use it. Turn on two-step sign-in.
An ID number cannot be changed, so lock it: a credit freeze or fraud alert in the US, a credit warning (kreditadvarsel) on borger.dk in Denmark, Cifas protective registration in the UK.
Your phone number is out: ask your mobile operator for a PIN or port-out lock, so nobody can move your number to another SIM card and take your login codes.
Your home address is out: be wary of letters, parcels or visitors that mention Technische Universität München, and of texts asking for a “delivery fee”.
Expect scams that use your details: calls, texts or emails pretending to be Technische Universität München, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
