About SigID
# About SigID
SigID builds hosted identity infrastructure for human users and autonomous agents. It combines OAuth 2.1 and OpenID Connect with passkeys, multi-factor authentication, enterprise SSO, first-class agent identities, cryptographic agent authentication, delegation, credential-vault access, wallet policy, x402 authorization, and tenant-scoped audit records.
The product deliberately separates public 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. Public API descriptions are generated from the Rust routes that serve the protocol surface.
SigID is developed in the open at <https://github.com/sig-id/sigid>. Product documentation is at <https://docs.sigid.org/> and the canonical public API specification is at <https://auth.sigid.org/openapi.json>. The operator has not yet published a corporate postal address or public telephone number; this page does not fabricate either.
