M$ Authenticator App Error “code is already used”

11th September 2024

This is an error on the Android App as MFA can still be setup using a different device.

Possible Solutions:

Use your backup phone to setup M$ Authenticator, then setup Google (or whatever) authenticator on your Main phone.

M$ Authenticator can use a “normal” QR code but then you may not be able to add the M$ code? not tested
