Changes to MFA (Multifactor Authentication)
Microsoft has made a change in its MFA service
System/service: Microsoft MFA
Microsoft has made a change in its MFA service to secure MFA login and prevent overload attacks that affect all users who use MFA for login.
The change is that when you log in and the service requires MFA, you will get a number displayed in the web browser. You have to enter the number or select the number that appears in the notification that appears in the Microsoft Authenticator application on the mobile phone.
