Enable Multifactor authentication (MFA) in ArcGIS Online

Summary

Please note the following:

• Enabling Multi-factor Authentication (MFA) resets all active logins in ArcGIS Online and applications including ArcGIS Pro active sign-in, and users are forced to link their MFA from their respective smartphones through authenticator app on their respective platforms – iOS and Android.
• This activity must be executed with proper planning considering its login impact.
• In this case, the MFA must be disabled, an Administrator must disable it from the same option where it was enabled from security settings.
