Registration

Use registration when a user should create a new organization without receiving an invite first. Users who are joining an existing organization should use an invitation flow instead.

Flow

1. The user opens https://your-authproxy/register.
2. AuthProxy stores a short-lived HTTP-only registration cookie.
3. AuthProxy starts authentication.
   • With one configured identity provider, AuthProxy challenges that provider directly.
   • With multiple providers, AuthProxy redirects to the standard login page so the user can choose a provider.
4. After a successful login, AuthProxy deletes the registration cookie.
5. AuthProxy redirects the user to Invite.Lobby.Registration.BaseUrl.

The /register path is only active when Invite.Lobby.Registration.BaseUrl is configured.

Configuration

{
  "Cratis": {
    "AuthProxy": {
      "Invite": {
        "Lobby": {
          "Registration": { "BaseUrl": "https://lobby.example.com/register" }
        }
      }
    }
  }
}

Property	Type	Description
Lobby.Registration.BaseUrl	string	Absolute URL for the lobby registration experience that creates the organization after AuthProxy sign-in.

Aspire

When you configure AuthProxy through Aspire, set the registration destination with WithLobbyRegistration(...):

authproxy.WithLobbyRegistration(lobbyResource, "/register");

// or use a raw URL
authproxy.WithLobbyRegistration("https://lobby.example.com/register");

This sets Cratis:AuthProxy:Invite:Lobby:Registration:BaseUrl.
