Join code, QR code and showing it on a projector
In the “Invite students to the class” box, you turn joining by code on or off, copy the code or link, and show a QR code for the whole class to scan. Changing the code makes the old code and QR stop working; students already in the class aren't affected.

Steps
- On the class page, click “Invite students / QR”.
- Check the status line: “Joining by code is open” means students can join on their own. To pause it, click “Disable joining”; to open it again, click “Enable joining”.
- Under “Class join code”, click “Copy code” and send the code to your students.
- Under “Direct join link”, click “Copy link” to send the link by message or email.
- In class: click “Show on projector” to enlarge the QR code; students scan it with their phone camera.
- If the code has leaked: click “Change code” → “Yes, change code”. The old code and QR stop working immediately.
Options and limits
- When joining by code is off
- New students can't join with the code, link or QR code. Students already in the class stay. The class page shows “Join code: Off”.
- Inviting from a list
- Invitations sent to students who already have an account (see the Import student list guide) also need joining by code to be on for the class.
