This is almost always a-bad-idea - very few websites need to have registered users, and if you are not giving "edit" capabilities (i.e. not running a forum) then you will want to disable user registration in Joomla 3.x.Here are the steps to perform for disabling new user registrations in Joomla 3 To disable user registration, set Allow User Registration to No, and then click the Save button in the top left of the page.
- Log into your Joomla 3.x Admin Dashboard (backend)

- Click on the Options tab
- Select the Components tab
- Switch Allow User Registration to No
- Click "Save"
