TC04 - Moodle tutorial for teachers
All Moodle users need a unique user ID (username) and a password. The system identifies the users by their username, and in combination with their password allows them to log in.
There is a variety of reasons for identifying and distinguishing users. First, not everyone can access the learning materials, or the system itself. The other important thing is to assign the users to their appropriate courses or curriculum, and to give the users their different roles in the system (administrators, teachers, students, etc).
Many methods exist to create a user account. For example the system administrator may register the students, though the system may also allow users to register themselves.
