Change your channel name or icon
Once you’ve connected your YouTube channel with a Google+ page or profile:
- The name on your connected Google+ page or profile becomes your YouTube channel name everywhere (on videos, comments, your channel title, etc).
- Your Google+ page or profile photo becomes your YouTube channel icon.
Google+ supports changing your name up to three times in two years. Please keep this in mind if you decide to edit your name. Find out more about Google+ names.
Note that it may take some time for the changes to update throughout the site.
