 Some supported video services provide a better experience when you are logged in. For example, if you use Twitch Turbo or are subscribed to a Twitch streamer, logging in prevents the video stream from showing an "An ad is currently playing. Come back after the break." message until the ad is over. Other examples are private or purchased YouTube videos which you can only watch while logged in.
