Description

Configure this policy to decide whether WAM is used for authentication in Microsoft Edge on Windows 10 RS1 and RS2. If you enable this setting, WAM is used in the authentication flow on Windows 10 RS1 and RS2. If you disable or don't configure this setting, OneAuth libraries are used instead of WAM on Windows 10 RS1 and RS2. If this policy is enabled, then previous sign-in sessions (which used OneAuth by default) can't be used. Sign out of those profiles. This policy will only take effect on Windows 10 RS1 and RS2. On Windows 10 RS3 and above, WAM is used for authentication in Microsoft Edge by default.
