Product Decisions This Supports

Enterprise SSO feature decision: Adding “Sign in with Okta / Microsoft Entra ID / Google Workspace / Keycloak” to a Laravel/PHP product without building the OIDC protocol from scratch.
Build vs. buy: This package supports a “build the integration, buy/use the customer’s IdP” path. It is a client library, not an identity platform, so it reduces protocol work but does not replace Auth0, WorkOS, Cognito, Keycloak, or similar.
Roadmap prioritization: A low-cost way to validate demand for SSO as an enterprise-tier capability before investing in SAML, SCIM, MFA, user directory sync, or a full auth vendor.
Multi-tenant auth design: Supports per-tenant issuer/client configuration, domain-based IdP discovery, callback handling, and token validation for B2B customers who bring their own identity provider.
Use cases: B2B SaaS selling to organizations with existing IdPs; internal Laravel tools standardizing on corporate login; products needing OIDC social/enterprise login without adopting a full auth platform.
Security/compliance planning: Enables server-side authorization code flow and ID token validation, but the product still needs session management, state/nonce/PKCE handling, key rotation, audit logging, and operational hardening.

When to Consider This Package

You have an existing OIDC-compatible identity provider and need a lightweight PHP/Laravel client for authorization code flow.
Your team can own the security integration: state, nonce, PKCE, callback validation, issuer/audience/expiry checks, session fixation prevention, logout, and key rotation.
You want a permissive Apache-2.0 dependency with a small surface area and are comfortable wrapping it in Laravel-native services, guards, and configuration.
You need generic OIDC support across multiple providers rather than a single social-login SDK.
Look elsewhere if you need SAML, SCIM, MFA, passwordless auth, user management, RBAC, audit logs, SLA-backed support, or a certified commercial identity platform.
Look elsewhere if you need a Laravel-native package with migrations, guards, socialite-style flows, and opinionated defaults out of the box.
Look elsewhere if your organization cannot accept open-source maintenance risk, requires vendor support, operates in a highly regulated environment, or lacks PHP security engineering capacity.

Executives: “This is a small, permissively licensed OIDC client that lets our Laravel product accept logins from customers’ existing identity providers. It is a fast, low-license-cost path to pilot enterprise SSO and avoid lock-in to a full auth vendor. It is not a turnkey identity platform: we still own security hardening, session management, and operations. Recommend a design-partner pilot with one IdP, then reassess managed auth if we need MFA, SCIM, audit logs, or an SLA.”
Engineering: “It is a minimalist OIDC client, not a Laravel package. We would wrap it in a service, configure per-tenant issuer/client credentials, implement state/nonce/PKCE, validate issuer/audience/expiry/nonce, handle key rotation and logout, and test against Okta, Entra ID, Keycloak, and Google. Apache-2.0, last release September 2024, moderate community traction; run a dependency and security review before adoption.”
