In addition to Admin and Main User Account, it is important that you create another User Account on your MacBook to deal with the possibility of being locked out of the Main User Account.
Another reason for creating an additional User Account on Mac is to allow children or others in the family to use your computer, without being in a position to make changes to files and settings, located in your own User Account.
