I run a forum (just starting out < 100 users). I have Google login (along with the traditional email signup).

I googled a little bit and found out that about 83% of social login are Google and FB.

The forum is custom built. I don't have the luxury of clicking checkbox and enabling an extension. I am planning to add FB login shortly. Is it okay that just ignore the other social logins?

Notes

[1] After i enabled google login i find that almost all new registrations use this option.

[2] That article is from 2015, is that data still relevant now?
