That's strange, I don't need one to install from FDroid or GitHub Store or Firefox. You need one for Play Store but you don't have to use that.

I don't have a Google account. No idea what you're on about, tbh.

I used to not use one either, and used Aurora Store for certain apps. But at some point, my bank's app stopped working if I installed it from Aurora Store, and would only work from the play store. Since then I've seen a lot more apps that work this way.

Well, banks will do bank things. Still not a general Android issue, righ? Though I wish the attestation would just check if the bootloader is locked and if there's no root. Then there wouldn't be an issue with ChatGTP, banking apps, some stupid airline apps that don't work on GrapheneOS.
