Waterfox Essentials: How to enable Windows SSO login in Waterfox

Windows single sign-on (SSO) is a new Waterfox feature that allows you to log in to Microsoft, work, and school accounts using credentials from your Windows 10 or 11 operating system. To enable it, click the Waterfox menu button, click Settings, select Privacy & Security on the left, go down to the Logins and Passwords section and check the box next to the Allow Windows single sign-on … setting.

Note

This feature is available to Windows 10 and Windows 11 users starting in Waterfox version 91. It may be expanded to other Windows users in a future release.

If you have accounts in the Accounts used by other apps section, Waterfox will use that information to log you in to Microsoft sites including Outlook and Office 365, as well as any work or school accounts that use Microsoft authentication.
