This article will discuss how we can set up an Office 365 account with Two Factor Authentication enabled and enforced via Text Message / SMS and simply provide the credentials to the user. The reason we are doing this is convenience for the end user as they don’t need to go to https://aka.ms/mfasetup before they are able to use the account. They can immediately add the account to their smartphone or Outlook.
Add the user as normal in the Admin Console as usual.
The next step is to head over to Azure Active Directory > Dashboard > Users > User > Authentication methods and add their mobile / cell number to the Authentication contact info
Head back to Admin > Multifactor Authentication and Enable then Enforce
You’re done. Simply provide the email address and password to the end user and it will automatically send the 2FA information to their mobile.
