End User Experience

Once Windows SSO is enabled in Firefox:

• Users accessing Microsoft 365 services such as Outlook, Teams, and SharePoint will be automatically signed in using their Windows credentials.
• Users will no longer be prompted repeatedly for usernames and passwords, streamlining access.
• This seamless authentication improves productivity and reduces login friction in enterprise environments.

Open Firefox on the device and follow the steps provided earlier in “Manually configure SSO on Windows 10/11. You can notice that the “Allow Windows Single Sign-on for Microsoft, work, and school accounts” option is now enabled and grayed out. The policy is now applied through Intune, and users won’t be able to change the settings.

Enabling Windows SSO in Firefox streamlines authentication for Microsoft, work, and school accounts, improving user experience and reducing repetitive logins. Whether configured manually or deployed via Intune, this feature is a valuable addition for both individual users and enterprise environments, enhancing security and productivity.
