Have this plugin installed on a site for years now and it has always just worked, with minimal maintenance. Thanks for the awesome plugin.

Works great if you’re willing to use PHP 5 or don’t need Linkedin. Really disappointing that it’s no longer updated.

OUTDATED NOT WORKING

I have by now tested all the other major solutions and must say, Miled’s Social Login is, in my view, clearly the best among social login plugins, even though it has not seen any major upgrade in roughly a year (by the time of this review).

It offers integration at all relevant points (login, registration, BuddyPress, commenting e.a.; even provides syncing of harvested info to X-Profile-fields with custom mapping; how awesome is that?) and does have none of the hurdles and artificial limitations that similar plugins by other developers impose, often to force you into buying their «pro» version/s.

I have only one minor grievance with user creation in the Facebook process [but I’m not even sure that’s Miled’s ‘fault’, since many other users seem to be able to work around that just fine; it may very well be owed to some peculiarity in my setup which I simply haven’t been able to pinpoint yet].

So, even more kudos to @miled (y) after having checked out the competition and playing with quite a few of those (way more than I actually care/d for); I can wholeheartedly say: Start with this one. You may very well have to look no further.

So it is not clear from the start whether you can use this with custom registration/logins. I couldn’t figure out a way, so I emailed them. No response. Nothing. Simple question.

Unless you want a plugin where a basic use case is not clearly defined up front and you don’t hear back about it, do not use/purchase this.

There are better options out there.
