However, at best this should be an interim solution until you are able to transition to Security Defaults or Conditional Access - all accounts without MFA represent a potential security risk as they are available with a single factor of authentication.

Otherwise, if you really can't get everyone using MFA such that you can't use Security Defaults, you can use this approach to selectively enable MFA, such as on high privilege accounts - this is much better than not using MFA at all if Security Defaults doesn't work for you. If you have Azure AD Premium P1 licenses, there is no reason to use Legacy MFA - you should be using Conditional Access as it provides all the same features and flexibility but with far better support. Users are prompted for MFA on every login, regardless of what they're accessing. It allows you to enable MFA per-user and to create exceptions where necessary but is only configurable via a separate legacy web panel or PowerShell. Once you’re signed into your account and on the Security info page, you can remove an existing method (if they no longer apply) by clicking the Delete link beside them, and you can add a new method by clicking the Add sign-in method link.Per-user (or legacy) MFA, as the name suggests, is no longer Microsoft's preferred option for using MFA in Microsoft 365.If you do not have a method available to authenticate then you will need to contact your Office 365 administrator for assistance and they can reset and request you provide new methods

Note: If you have issues signing into your account because you’ve replaced your phone and can no longer approve a sign in via an app like Microsoft Authenticator, try clicking the I can’t use my Microsoft Authenticator app right now link and see if you can use an alternate method such as a phone call or SMS.

Sign in to the Microsoft My Sign-Ins page by visiting Īlternatively you can sign in to then click your profile picture (or initials) in the top-right of the page, click View account then under Security Info click Update Info.
