About SigID¶
SigID builds hosted identity infrastructure for human users and autonomous agents. The product combines OAuth 2.1 and OpenID Connect with passkeys, multi-factor authentication, enterprise SSO, first-class agent identities, cryptographic challenge-response authentication, delegation, credential-vault access, wallet policy, x402 authorization, webhooks, and tenant-scoped audit records.
The system deliberately separates public product discovery, personal account management, tenant administration, hosted authorization, and documentation across dedicated origins. That topology gives users, developers, and automated clients an explicit trust boundary before they send credentials or change state. Protocol-critical flows are served by the Rust service, and the public OpenAPI description is generated from the same route definitions.
SigID is developed in the open at https://github.com/sig-id/sigid. The public API schema is available at https://auth.sigid.org/openapi.json, with a documentation mirror at https://docs.sigid.org/openapi.json. Security reports, privacy requests, and product questions use separate contact routes. The operator has not yet published a corporate postal address or public telephone number; the documentation does not fabricate either.
