> The newer app versions refuse to run without Google Play Services, but you can still make a throwaway andorid emulator with GPS.

Can't you run GPS on a rooted phone, or am I mistaken? (If not, what about with magisk?) I suppose if it will run on a phone with an unlocked bootloader, you could always keep it unrooted until you need to copy the hotp, then root it.

Amazing that they've managed to rent-seek on top of a freely available open standard.
