How to Create Registered Users in Joomla
The most basic users in Joomla — beyond mere web surfers who happen by your site — are registered users. This group, which comes as a part of your default Joomla installation, can log in to your site (using the login box that appears on the front page by default) and see resources reserved for registered users.
Joomla provides two ways to create a registered user:
The administrator creates the user’s account in User Manager.
The user herself can click the Create an Account link in the login module on the front page and then fill out a registration page.
User-created accounts on Joomla sites
Joomla has a few different options for how it handles the creation of a new user account. The default is self-activation. Under this setting, after the user creates her account, she will receive an email sent out by the CMS. By following the e-mail’s instructions, the new user can activate her account by herself without the aid of a site administrator.
Joomla can also be set up to automatically activate an account as soon as it is created — with no need for the user to do anything but enter their account information.
Finally, for those of you who prefer to keep both hands on the wheel at all times, there is a setting called Admin, which when selected, will not allow a new user account to be activated until it has been approved by a user with administrator privileges.
If you opt for either email or administrator activation, a non-activated account will be shown in the User Manager as — you guessed it — Non-Activated.
To change the way that Joomla handles new account activation for your site, click the Options icon in the upper right-hand corner of the User Manager window. In doing so, you’ll open the Users Configuration window.
The default user group for newly registered users is Registered, but you can change this to Author, Editor, Publisher, or any of the groups you may create specifically for your site. Click on the Options icon in the top-right hand corner of the User Manager window. Look to the drop-down list titled New User Registration Group, and adjust the settings to suit your needs.
Administrator-created accounts in Joomla
Besides allowing users to create their own accounts, you can create accounts for them with User Manager. Once the User Manager: Users page opens, follow these steps:
Click the New button in User Manager.
The New User page opens.
Enter the account information for the new user.
Click the Save & Close button.
Joomla creates the new account and takes you back to User Manager: Users, where the new registered user appears. The user can log in immediately and view resources that you’ve marked as needing registered privileges.
