As clunky as one would expect, given the legislation, but functional. Please add a language option separate from the system language, as the English localisation is, as always in Germany, terrible, and I would much rather use a comprehensible German UI.

Laughable Bad Tends to ask for the PIN at each single step of the authentication process, not just the beginning. Hangs in a never ending loop without proper timeout. Generic error messages that don't provide any info. I know how two factor authentication is supposed to work. This is not it. I don't have any clue how tech iliteraterate people are supposed to work with it Definitely don't want to hear anything more about low acceptance of ePA in Germany if this is it Its a joke

If you see an error, please reinstall the app. In the app, you create your own PIN and then identify yourself. Once the app is set up, it can be used to authenticate other applications, such as the electronic patient record.
If you have any questions or need help, just drop us a line at technischer-service@tk.de.
Best regards, TK-Ident App

It worked great, but now unfortunately security theater was added, not allowing me to use the app on GrapheneOS. RE to the reply: GrapheneOS is more secure than the stock OS. There is guidance available on their website on how to implement attestation to satisfy legal requirements and not exclude GrapheneOS.
