i liked https://wordpress.org/plugins/oa-social-login/ before i went to another solution
im not sure if it has integration with bbpress or not though.
and this requires an account to their website.
https://wordpress.org/plugins/loginradius-for-wordpress has bad support and i couldnt get the plugin to work well when i tried it.
you can also find some paid social login plugins in codecanyon , im for sure there is one that offers social login and has compatibility with bbpress. I think it cost like 28 dollars or something close to that.
