Enable implicit sign-in

Configure this policy to allow/disallow implicit sign-in. If you have configured the 'BrowserSignin' (Browser sign-in settings) policy to 'Disable browser sign-in', this policy doesn't take any effect. If you enable or don't configure this setting, implicit sign-in is enabled, Microsoft Edge attempts to sign in the user into their profile based on what and how they sign in to their OS. If you disable this setting, implicit sign-in is disabled.
