OpenID Connect identity provider

In this document you’ll learn more on using WVS as an OpenID Connect identity provider to sign in to other services.

Introduction to OpenID Connect

OpenID Connect (OIDC) is a simple identity layer on top of the OAuth 2.0 protocol. It allows clients to:

  • Verify the identity of the end-user based on the authentication performed by WVS.
  • Obtain basic profile information about the end-user in an interoperable and REST-like manner.

OIDC performs many of the same tasks as OpenID 2.0, but is API-friendly and usable by native and mobile applications.

On the client side, you can use OmniAuth::OpenIDConnect for Rails applications, or any of the other available client implementations.

The WVS implementation uses the doorkeeper-openid_connect gem, refer to its README for more details about which parts of the specifications are supported.

Enabling OpenID Connect for OAuth applications

Refer to the OAuth guide for basic information on how to set up OAuth applications in WVS. To enable OIDC for an application, all you have to do is select the openid scope in the application settings.

Shared information

The following user information is shared with clients:

Claim Type Description
sub string The ID of the user
auth_time integer The timestamp for the user’s last authentication
name string The user’s full name
nickname string The user’s WVS username
email string The user’s email address
This is the user’s primary email address if the application has access to the email claim and the user’s public email address otherwise
email_verified boolean Whether the user’s email address was verified
website string URL for the user’s website
profile string URL for the user’s WVS profile
