Even if you never intend to use your YouTbe account to create your own channel and publish videos, there are various advantages to creating and using one. You can do the following using a YouTbe account:
On the home page, you'll get tailored recommendations for videos to watch based on your viewing history.
Subscribing to your favorite channels will allow you to quickly access their most recent videos.
When channels upload new videos, you'll get notifications.
Interact with the videos of your favorite creators to show your support (liking them and leaving comments).
Keep track of how many times you've watched a video.
Videos can be saved to be watched later.
Make your own video playlists, either public or private.
Customize your notification, playback, privacy, connected apps, and other user preferences.
