You can lock your class(es) so that no more students will be able to join even if they have the join code. You can quickly unlock/re-lock your class(es) to allow new students to join. Tip: Locking your class(es) will also prevent you from making any accidental changes.
- From your "Classes" tab, select the class you'd like to lock.
- Click on the "Lock" icon at the bottom of the page.
