Add-on OAuth2 login


Active member
I would like to be able to add a OAuth2 login on my site. (Blizzard provides a login service for their service). (docs are here )

Is there any addon that could be used or do you have any suggestions on where I can get started on adding it myself. Ideally I should be able to set the scope so that my site can ask for the permission to view the persons characters on the game site.
