OAuth Member Login

It would be amazing to be able to add a custom OAuth service provider to the member's login and sign up area. For example, I could use my client secret and what not from Slack and Slack user's would be able to sign into the forum on my Wix website. This would be gold and be very appreciated. Or at-least given more API hooks for developers which regards to members. Then someone could use that to integrate this whether or not it comes from Wix.
