Due to maintenance on the central authentication backend, logging into the Uni Bonn App will be temporarily unavailable on Wednesday, May 13th, 2026, between 6:00 a.m. and 7:45 a.m.
We recommend that you log in to the app the evening before so that you can access your library card in your wallet during the maintenance.
You may need to relink your library card to the Uni Bonn App after the maintenance work is complete.
