A-Trust Signatur

Mostly entirely Flawless. The registration process takes some time, that is an appointment at the appropriate government Office.

I hate to leave a lone-star review, but as most people have said, this app is awful. Over-engineered, over-complicated. The only thing it's meant to do is verification, and it can't even do that. It's incredibly slow, even on a fast phone. And when you do finally get the app to work (and this might be multiple attempts and about 20 minutes), the corresponding web pages rarely work. I am now stuck in an infinite loop of entering my (correct!) social insurance number and tax number trying to link my Handy-Bürgerkarte to my Finanzamtonline (HOW ARE THEY NOT AUTOMATICALLY LINKED ANYWAY???). A-Trust, if you're reading this, find someone else to design you the app. There are so many apps out there which are even more secure but actually work - and they work instantly, every time. Find the people who made the Revolut app and hire them instead. If anything is unclear, feel free to contact me (after all, you have all of my data...)

Does what it's supposed to do but nothing more. Doesn't even have any notifications when your certificate is about to run out. But hey it's fine, at least you can read about it in the FAQ and you will be happy to see that you have to do a full re-registration in case you haven't logged in at least once during the 30 days before the certificate runs out... Will adjust rating to 4* when this is fixed.
