Setting Up Your Google Account
If you’ve signed into any of these products before, you already have a Google Account. To sign in, enter the email address you entered on those products (if you use Gmail, it’s your Gmail username). If you don’t have a Google Account, you can create one on YouTube.
A Google Account gives you access to Google products like Gmail, Google+, YouTube, and more with a single username and password. A Google Account comes with a Gmail address and a Google+ Profile. Once you create a Google Account, you can use that same username and password to sign in to any Google product.
Here are a few important things to remember about Google Accounts and YouTube:
1. You sign into YouTube with your Google Account. To sign in to YouTube, enter your Google Account email and password. After signing up for YouTube, if you sign in to your Google Account on another Google service, you’ll be automatically signed in when you visit YouTube.
2. Deleting your Google Account will delete your YouTube data, including all videos, comments, and subscriptions. Before you can delete your Google Account, you will have to confirm that you understand that you’re permanently deleting your data on all Google services, including YouTube.
With a Google Account, you can access many YouTube features, including Like, Subscribe, Watch Later, and Watch History. YouTube can also recommend videos based on what you’ve watched, liked, and subscribed to.
