REQUEST: Steam login for mybb

Hello. I'm looking for someone to make or someone that has a steamlogin plugin for mybb. I'm willing to pay if you're making it. It needs to have a database so it's compatable with this gmod addon:https://www.gmodstore.com/scripts/view/5307 . I don't want to get rid of the origional login system I just want them to be able to link everything with theirs.

I don't know if this help but there is a plugin that allows users to login with steam/battle.net/faceboo/yahoo/twitter and so on.. u can check it here https://www.oneall.com/ It have a mybb plugin and is well documented. Hope this helps you.
Cheers!
