If your site has been configured to allow self-registration, but requires the approval of an administrator for all self-registered users, you must approve those users before they can log in.
To approve users with pending registrations
By default, the Pending Registration page lists all users requiring self-registration approval:
The list of pending users is filtered to include only those that match the criteria you specified.
Note: To view additional details for a user, hover your mouse over the user name. To change the sort order for a column, click the column header. To restore the view to include all pending users, click Refresh Display.
An email is sent to each user with their username and password to sign in to the site.
An email is sent to each user informing them that their self-registration request was rejected.
