If you need to add a large number of users to your site, the import feature can be very helpful.

Go to Manage > Users from the admin menu.

At the top of the user list, click the three-dot icon and select Import Users.

Prepare a CSV file. This file must include at least the columns: Username, FirstName, LastName, and Email.

Upload your CSV file.

In the next step, you can choose whether to send a welcome email to new users.

Complete the process. The users will be automatically added to the site.
