CTA modes
Popup
Log in opens a compact form that posts to Joomla Users with CSRF token and return URL. Configure the popup in Content - Easy Lock > Popup login: title, note under the heading (for demo logins), Remember me, Register now, Forgot username, and Forgot password. Each of those can be turned on or off. Buttons remain real links if JavaScript is off.
Same-tab link
Buttons go to login or register with return. After success, the visitor lands on the same article unlocked.
New tab
Same URLs with target="_blank". The card shows a refresh hint.
