Lock a Space
You can easily restrict access to a Space you have created by locking it. Make sure you are signed into your teacher/organization profile and navigate to your Spaces list at https://www.thelessonspace.com/ From here you can click on the three dots next to the Space name then select Lock to lock the Space.
You will then be asked to create a lock, this is to determine which students have access to it and in what time frame. Note- all fields are optional but if no fields are filled in then the space will be locked to all students indefinitely.
