Apparently, the code(s) generated by an OTP app also carry a version number with them. I am using andOTP, and get the following error message from the login page:
Duo Mobile None is not allowed by your administrator. Please update to Duo Mobile 3.8 or above and try again.
I wonder if this is something that can be addressed in the future versions of DuOTP. Thank you!
I'm trying to get this to work on my new de-googled phone (and I tried it on my old googled one too). I installed the apk from Fdroid, got the link from my employer, and when I tried to open the link, it allowed me to select duotp instead of duo mobile. I selected DuOTP, but it failed with "an error occurred".
For reference, I tried with Aegis first, then Google Authenticator, but no dice on either one. If you wouldn't mind, could you provide some guidance here? I'd really love to get this working :)
