⚠️ Multi-Factor Authentication (MFA) Setup Issues

Cause: Problems during the initial registration or subsequent use of MFA.

⚠️ Accessing Multiple Accounts (e.g., Student Worker)

Cause: Attempting to open both student and worker Office 365 accounts simultaneously in the same browser session can lead to conflicts.

Solution: To manage multiple Jefferson Office 365 accounts at once, use different web browsers (e.g., Chrome for one, Firefox for another) or utilize your browser's private/incognito mode for the second account. Always use the official Jefferson login links and avoid generic Microsoft email portals.
