My workplace requires me to login with an authenticator app, but they also “required” me to use the Microsoft Authenticator App (jokes on them, I use Aegis Authenticator).
How I manage to get around this is by carrying not one, but TWO dumbphones on me. (Depending on your dumbphone, only one would be required.) My main dumphone (Sonim XP3 Plus) is perfectly compatible with my carrier (T-Mobile), but it can’t install apps/APKs. My secondary dumbphone (Kyocera Digno 902kc) isn’t compatible with my carrier, but it ABSOLUTELY CAN install APKs.
Depending on your dumbphone, you might not need two like me. You probably only need one. You might not even need a Japanese Flip Phone as your secondary. As long as it connects to WiFi and can install APKs, you’re good.
How unfortunate. Just trial and error, I suppose. What dumbphone do you use, now?
