I wanted to use the Google Authenticator app to set up two factor authentication. However when I click on the button to scan a QR code, it opens up a camera with 'NAB Banking' at the top (my internet banking app). When I scan a code, it says 'Oops! This isn't a valid BPAY code.' (see screenshot below)
Is there some settings related to using the camera for QR code scanning, that my internet banking app has taken 'hostage'? (That I might hopefully be able to clear?) I didn't have the NAB app open at the time, and as far as I remember I have never used the QR code scanning from within it.
- Google Authenticator 2.49
- NAB: 3.0.1
