Generic Oauth2 authenticator

[dmvieira]

Hey guys, why we don't have a default implementation for oauth2?

There is a base class that implements the common parts (oauth2.OAuthenticator). There's a last step needed for turning the access token on the callback into a username, which seems different for each provider. That's the only difference between them right now. I'm not aware of a generic implementation of this. Is there a generic way to ask an oauth provider the username corresponding to an access token?

[dmvieira]

Yes, there is an RFC https://tools.ietf.org/html/rfc6749#section-4.4

I'm doing here ;)
