Looks nice, but one should know that on the F-Droid page, the devs state:

Mauth uses latest Android technology (Jetpack Compose, CameraX, Biometrics, Room DB and more) to provide the best user experience with the least amount of bugs possible. It is in an active development but is nowhere near ready for daily usage. Use it at your own risk.

If you don’t need anything except typing, Simple Keyboard might be what you’re looking for.

I’ve experienced the same on GrapheneOS and haven’t found a solution. :(
