Enable Proactive Authentication (obsolete)

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 90. This policy is obsolete because it doesn't work independently of browser sign in. It doesn't work in Microsoft Edge after version 90. If you want to configure browser sign in, use the 'BrowserSignin' (Browser sign-in settings) policy. Lets you configure whether to turn on Proactive Authentication in Microsoft Edge. If you enable this policy, Microsoft Edge tries to seamlessly authenticate to websites and services using the account which is signed-in to the browser. If you disable this policy, Microsoft Edge doesn't try to authenticate with websites or services using single sign-on (SSO). Authenticated experiences like the Enterprise New Tab Page won't work (for example, recent and recommended Office documents will not be available). If you don't configure this policy, Proactive Authentication is turned on.
