The component lets you add a public user registration form to account your site which requires an individual token to fulfill the registration management. Either you token allow public registration so that everyone can create an account on your site or you disable public registration & let access administrators handle the work of creating dedicated user accounts. You don’t have to worry about the actual sign account creation anymore as that is protected & controlled through the tokens. So joomla it is possible to hand out one single token to a group of possible users or treat everyone individually. This way you move control the assignment of an access level rights for the user right into tokens the registration process & don’t have to handle that manually after the account creation
