They also said it was mandatory for all the students and teachers to use the stupid 2FA Microsoft app on our phone, but I’ve been using Keepass on desktop without problems (and even shown it to some students).
Yeah if they’re just using the MS app for OTP generation, there’s no reason to use that specific application. Keepass is perfectly fine.
Asahi is pretty great. Only issue for me personally is the lack of speaker support. Audio works fine through headphone jack or bluetooth though.
