Ability to connect with OAuth providers when user is registered?

Feature

I think “disassociate” means simply removed associate oauth uid and user_id in local.

One more problem is that oauth credentials can be expired. The provider may ask for re-authorization. (When a plugin author wants to use the oauth2 credentials to trigger API, they would like to know this situation)

According to those 2 problems, an Authenticator has to report association and expiration information. They are simply trying to find a user record implicit.

Now, Discourse has {google,facebook,github,instagram,twitter}_user_info. Plugins can use oauth2_user_info or PluginRow. I would say a new model can represent all those information, for instance:

  • uid, comes from provider
  • email
  • name
  • access_token
  • refresh_token
  • expired_at
  • CustomFields or a JSON field, can use for other information storage.

Then a simple query can get a list of associated providers for the user. Disassociation is simply done by remove this record.

Beyond that, Authenticator have to provide functions to determine:

  • is there a existing user
  • is the token fresh
