Dev note

Steam uses OpenID 2.0 spec (2007):
https://openid.net/specs/openid-authentication-2_0.html

The spec was replaced in 2014 by OAuth 2.0 based OpenID Connect (2014):
https://openid.net/specs/openid-connect-core-1_0.html

Steam does **not** use OpenID Connect.
All "certified" libs linked by Steam implement OpenID Connect, not OpenID 2.0.
