3. Access Code

If you have set your space Access Level to 'Restricted to members' you can assign an access code here. If a user who is not a member of your space tries to access it then they will be asked for this access code. If they enter the correct code they will be automatically made a member.

This is an easy option to enrol people in your space/course, rather than having to enter their usernames into the members list just email them all the access code and they can enrol themselves.
