Administrator username and password

Hi,

You can add a new user to the Mac from within Preferences

On your Mac, choose Apple menu> System Preferences, then click Users & Groups.

Click the lock icon to unlock it. Enter an administrator name and password.

Click the Add button + under the list of existing users.

Click the New Account pop-up menu, then choose a type of user, you want an administrator.

Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.

Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.

Click Create User.

All done

Note that you must be an administrator to create one.
