Authress

Authress is a “login and access control API” that combines authentication (hosted UI, social/enterprise SSO) with authorization (granular, role- and resource-based access) for application builders. It issues JWT access tokens and exposes SDKs/APIs to verify and enforce permissions from code.

Key Capabilities

  • Standards-based SSO & Identity: Integrations for SAML, OpenID Connect, and OAuth 2.0; supports enterprise SSO per tenant. Hosted login UI with social login, passwordless, WebAuthn/passkeys.

  • MFA / WebAuthn & Passkeys: Passwordless login and FIDO2/WebAuthn supported as part of the hosted login experience.

  • Token Services: Issues EdDSA-signed JWT access tokens; guidance for server-side validation using Authress public keys. Machine-to-machine auth and API key (“Service Clients”) issuance are built in.

  • Audit & Observability: Built-in audit trail of logins/authorization checks; streaming to AWS EventBridge and GCP Pub/Sub; dashboard in the management portal.

Limitations

  • SCIM user provisioning: Authress documentation mentions “SCIM and IdP syncing” among less-common login/user management options, but there is no dedicated, vendor-authored SCIM API/connector guide confirming a production SCIM 2.0 endpoint.

  • Compliance attestations: No vendor-hosted SOC 2/ISO attestations or trust center were found in public docs.

  • Ecosystem maturity signals: Limited third-party analyst coverage; most capability details are vendor-authored.
