Hi Danelle,
If you are using the TOTP code instead of passwordless (i.e. prompt to allow access). This can be incorrect due to the date / time on your device due to the code refreshing every 30 seconds. Therefore, this would be worthwhile confirming the date and time are correct.
If this is still not working, I would suggest removing and re-adding the authentication method and re-testing as per the below:
Kind regards,
Sam
