I’ve nearly decided to switch back to the code brick instead of BankID app. It’s less convenient, but with the way things are going, I’m just not sure I want to exist in the digital world much longer.
I switched to GrapheneOS a couple months ago, and the only real downside is that MitID (danish verison of BankID) doesn't work. I got the code brick and attached it to my keyring and it's honestly not that bad, I usually have the keys close by anyway. Also most apps that need MitID allow you to create a pin to log in without reverification once you've logged in once.
