Logging into Oculus account from custom webpage/app??

Is it possible to integrate an Oculus login into a custom webpage, like you can with facebook or google?
The game I am creating is going to have a companion app/web portal that talks directly to the game, and I would like for my users to be able to log in with their Oculus accounts. 

Similar to this: https://developers.google.com/identity/sign-in/web/sign-in for google auth.

It's easy enough from within unity using "Platform.Users.GetUserProof()", I'm looking for a way to get the same info via web.
