@Kelly said in Office365 MFA vs 2FA:
2FA is really no longer a thing (if I'm understanding what you're talking about). MFA is the means for utilizing additional means of authentication. MFA is a superset of 2FA. If you disable MFA then you're disabling 2FA effectively.
I was just really confused by the whole delivery of this setup. I have configured and migrated to a ton of O365 setups and something was just unnecessarily difficult with this one. I understand now that the newer versions of Outlook support MFA and connect much easier than say an iphone. On the iphone, it would redirect and tell the user they have 14 days to setup MFA. If you proceed with setting up MFA the user has to download the MS Authenticator app and then flip back and forth to add their code and copy and paste a url. The redirection asks they scan the bar code but can't really scan a bar code on the screen of the device you are setting up. I assume the proper way to set with up would have been to have the user login to a computer first and get their authenticator setup before adding the account.
I agree that multifactor should be used but if they are going to require it by default, there should be a better way to get the users setup.
