Can i set an alias ?

One suggestion would be to use our Automatic Registration setting. Instead of going to this mini-registration page, the user would automatically be created. Beyond that, no, we don't have a recommendation on how to change that URL. It's only shown during registration and generally shouldn't be indexed by search engines because no URLs link directly to that page. There are SEF extensions and other options that could let you setup a redirect from that page to another URL you'd want to use, but that would be setup in those extensions and not JFBConnect. With that said though, we recommend not using SEF extensions to alter most JFBConnect URLs because some social networks are extremely picky about URL structure and even the slightest change in structure can cause them not to allow authentication.

Sorry we don't have a better answer, but this just isn't something that's been brought up before so it's not something that we've worked or thought through a solution for.

Going forward, I'd suggest you look at the "Auto Username Prefix" setting in JFBConnect to choose a different format of the usernames from fb_ to something like first.last name. This will generate better usernames for you.

I just went to the Joomla users component on the frontend (index.php?option=com_users&view=profile) and changing the username is not an option when editing your profile. JFBConnect doesn't expose a way to change the username, as it's just a standard Joomla user after you've created and then we have a table to map the Joomla user to the Social Network user - you can see the mapping in JFBConnect backend > User Map area. If you already expose a way for the user to change the username, the mapping from the Joomla user to the social network user still works, since it's based on user id.

I'm not sure what you mean by it's bigger than Facebook. Twitter, LinkedIn and most other social networks allow importing the user's email address. If automatic registration is enabled, then they will bypass the login or register page.

Some networks, like Instagram, don't allow the email to be imported though. You can make a code adjustment to force an Itemid onto that URL. That Itemid could be for any menu item you have and then you could assign modules to that menu item just for JFBConnect. To do so, edit the /components/com_jfbconnect/controllers/login.php file. Around line 123 you'll see:Update that with the right Itemid, like:
I hope that helps,
