Thank you for reaching out to the Community! I apologize for any confusion there may be with your account's users all being registered with the same email. The good news is you can definitely remove or update your users as you see fit. This is something you can do under the My Account section of your account.
Under the Account Users section, on the right-hand side you will see "Manage Users."
This is where you can make your changes.
