← All capabilities

sign-in

OAuth identity providers (Google, GitHub, etc.) and SAML/OIDC bridges.

The CLI flag value is --capability auth-provider (the internal name); the marketplace surfaces it as “sign-in”.

Build one

Scaffold a new provider for this capability:

vincia create connector my-auth-provider --capability auth-provider

Read the connector guide for the full lifecycle (scaffold → test → publish), or the API reference for the interface contract.
