Identity Vision

Why This Exists

This document defines the long-term vision for the Identity Domain.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Identity makes Algosure safe to use for real procurement work. It protects sensitive business data, supports team collaboration, enforces subscription-aware access, and preserves tenant boundaries.

Vision Statement

The Identity Domain will become the trusted access control foundation for Algosure. It will authenticate users and services, authorize actions, enforce tenant isolation, support MFA, govern API access, and provide auditable decisions across every domain.

Identity Principles

  • Every actor must be authenticated before access.
  • Every action must be authorized before execution.
  • Tenant boundaries must be enforced consistently.
  • Access must be least privilege by default.
  • Sessions and API keys must be revocable.
  • MFA must be available for higher-risk access.
  • Authorization decisions must be explainable and auditable.
  • Implementation providers must not define the business language.

Future Identity Model

    Actor[User or service actor]
    AuthN[Authentication]
    Session[Session or API key]
    Tenant[Tenant boundary]
    AuthZ[Authorization decision]
    Resource[Domain resource]
    Audit[Audit trail]

    AuthZ --> Resource
    AuthZ --> Audit

Keycloak Compatibility

Future Keycloak integration may support identity brokering, federation, OAuth2/OIDC flows, token management, or centralized identity administration. The domain must remain portable: if Keycloak is replaced, the Identity Domain concepts should still stand.

Definition Of Success

Identity is successful when:

  • Users can securely sign in and collaborate in the right organization.
  • Invitations create controlled membership access.
  • Roles and permissions are understandable and enforceable.
  • API keys are scoped, auditable, and revocable.
  • MFA reduces account takeover risk.
  • Billing entitlements are considered during access decisions.
  • No tenant can access another tenant's data through identity failure.
