Overview
If you no longer want people creating their own accounts through your registration link, you can switch self-registration off at any time. Once disabled, the link stops working — so anyone who still needs an account will have to be added by an admin.
Step-by-step instructions
Go to your Atlas admin page.
Go to Users in the left-hand menu.
Click the three dots on the right, then select Configure Self Registration.
Select Off.
Note: If you turn self-registration back on later, the link changes — so remember to update any communications that include the old link.
