This is a great feature. I just enabled it, and it works just fine. However, I was a bit confused when I didn’t see any backup codes generated until I realized that the SMS/Call method is, in this case, the backup method. So, while it is more convenient to use an MFA app, I’m not sure about the security if the SMS method is still an option.
Thank you so much for sharing this valuable information! Your input is greatly appreciated.
