Walk in without an appointment to set or change your online-ID PIN, free of charge.
Bring your valid identity card. If changing a known transport PIN yourself, use the official AusweisApp. Ask the counter which procedure applies if the PIN is lost rather than assuming that an app-only change is possible.
