In recent years, Microsoft has been strengthening the security settings of Microsoft accounts as part of its policy.
Due to these security enhancements, users may be required to undergo multi-factor authentication (MFA) when signing in to Microsoft 365 (including email, Teams, Office, etc.), regardless of their individual settings.
Therefore, when signing in to Microsoft 365 with your university Microsoft account (@u or @un), if you encounter situations such as:
Being prompted for multi-factor authentication, or
Being asked to set up the Authenticator app,
please refer to the following university web pages for assistance.
※ Your UTID and password are required to access it.
