Please Note:

Please make sure you set up other alternate MFA methods.  With only the Microsoft Authenticator method in place, you must have access to the device you installed it on and remain logged into the app to sign in.  It is very important to have these authentication methods in place, but the only way to reasonably prevent most issues with MFA is to also have a phone number and email address set up as well.

If you require further assistance with configuring MFA, please contact your IT Support for help.
