“How do I hide my real name and use a user name for my Youtube account?”
1. Log into your Youtube account.
2. Go to the top-right corner of the page and click on your ‘Profile’ image. Select ‘Youtube Settings’ (or ‘Settings’ if you don’t have Google+ connected) from the drop down menu.
3. On the Overview page select ‘Advanced’ next to your profile.
4. If you have Google Plus connect to your Youtube account you’ll need to disconnect it by clicking on the link.
5. Now you can create a custom URL. Type in the user name that you want to use, remember this will also be your personal Youtube URL address. Click ‘Create Channel URL’.
6. If that url is available you should see a green check. To remove your real name and use your new user name click on ‘return name to ‘yournewyoutubeusername’ and disconnect google+ profile (if you haven’t already).
Now instead of your real name or Google Plus name you should see your new Youtube user name. Steps might be slightly different depending on your Settings.
