The youtube brand account is an option that provides your enterprise or brand a YouTube existence of its own. It’s another account from the private one which uses your own business or brand’s title, even though it’s still obtained via your private youtube accounts.
Why you must have a brand account and you need to switch from a Personal account to brand account?
As you grow, you can add moderators and administrators to your YouTube channel account without sharing your personal information without sharing your details, that’s another good thing so you can have a Virtual Assistant (VA) helping you out with your channel or you know uploading your thumbnails and editing, doing SEO for you or something like that along the lines and without being at risk of losing your account of sharing your account details.
