Why do I keep being asked to log in with Multi-Factor Authentication when logging into FYI?

Issue
When logging into FYI, I keep being asked to log in with my authenticator.

I have set "Stay signed in for 30 days" but I am still being asked to log in.

Cause
Multi-Factor Authentication is turned on in your Microsoft 365 account.

When Multi-factor Authentication is turned on, users in your organization need to enter the authentication code to verify identity when they log into Office 365 on the browser. This is actually a default behaviour.

Solution
If you feel this is an inconvenience, a Microsoft365 admin user has the option to bypass Multi-Factor Authentication verification. For more details, you can refer to Remember Multi-Factor Authentication part in the Microsoft help article Configure Azure AD Multi-Factor Authentication settings.
