Expand description

When an authorization code, hybrid, or implicit OAuth 2.0 Flow is initiated, Ory asks the login provider to authenticate the subject and then tell the Ory OAuth2 Service about it. Per default, the login provider is Ory itself. You may use a different login provider which needs to be a web-app you write and host, and it must be able to authenticate ("show the subject a login screen") a subject (in OAuth2 the proper name for subject is "resource owner"). The authentication challenge is appended to the login provider URL to which the subject’s user-agent (browser) is redirected to. The login provider uses that challenge to fetch information on the OAuth2 request and then accept or reject the requested authentication process.
