Is anyone working on fixing this? We can do so much better.
If they start selling their own devices, I will buy one and (assuming it turns out how I hope it will) recommend it strongly.
There is also an alternative for now, but nothing as simple as SMS or authenticator app. They give you a special credit card shaped card with a card reader that you can use to authenticate with using your PIN, which is mostly considered legacy now with the bank app. It's also not realistic to be carrying this thing around everywhere either as it's bigger than my phone.
There is also a national ID app that is used everywhere that I'm worried will stop working on GrapheneOS... Because without it I won't even be able to access online government services like healthcare, taxes, etc.
