Product Decisions This Supports

Build vs. buy vs. adopt for authentication: Supports a decision to avoid custom auth for low-risk PHP apps by adopting a small MIT-licensed library, while making clear that Laravel teams should generally default to Laravel’s first-party auth stack.
MVP and prototype scoping: Useful when email/password registration, login, logout, password reset, and basic account flows are necessary but not product differentiators.
Roadmap prioritization: Lets the team defer investment in a custom identity platform and redirect engineering toward core product features.
Non-Laravel PHP services: Best fit for standalone PHP tools, internal admin panels, small customer portals, and legacy PHP additions where no framework-native auth exists.
Laravel build decision: In a Laravel product, this package is not the default candidate; Laravel Breeze, Fortify, or Jetstream usually provide better integration, conventions, and maintenance.
Security risk review trigger: Adoption should force explicit decisions on password hashing, session handling, rate limiting, email verification, password reset, account enumeration, and security patch ownership.
Exception-path approval: Reasonable only as a timeboxed prototype or internal tool, or when a team explicitly accepts ownership of a small standalone auth library with an exit plan.

When to Consider This Package

Consider it when the product is a small, low-risk PHP application that is not Laravel-native and needs straightforward email/password authentication without SSO, MFA, social login, or complex role management.
Consider it when the team can review and own security updates, pin versions, monitor the repository, and wrap the library behind an internal auth interface.
Consider it when the database schema and PHP version requirements are acceptable and the team has verified compatibility with the target runtime.
Consider it as a reference implementation or spike to estimate auth effort, not as a long-term platform commitment without maintenance review.
Look elsewhere for Laravel applications where Breeze, Fortify, Jetstream, or Laravel’s native auth primitives fit: they reduce integration risk and align with framework conventions.
Look elsewhere if the roadmap includes MFA, SSO/SAML, OAuth/social login, enterprise RBAC, audit logs, compliance requirements, high-scale email deliverability, or managed identity.
Look elsewhere if the team cannot accept the risk signals: only ~1.2k stars, 0 dependents, no Laravel integration, and no clear ongoing security/maintenance commitment.
Look elsewhere if authentication is customer-facing, security-sensitive, or revenue-critical and the organization lacks in-house security review capacity.

Executive summary: delight-im/auth is a lightweight MIT-licensed PHP authentication library that can accelerate low-risk internal tools and prototypes. It is not a strategic identity platform and should not replace Laravel’s first-party auth stack without a security and maintenance rationale.
Engineering summary: The package is framework-agnostic, not Laravel-native. For Laravel products, standardize on Breeze/Fortify/Jetstream; if adopted elsewhere, isolate it behind an internal interface, pin versions, add integration tests, and assign an owner for security updates.
Product recommendation: Allow delight-im/auth only as an exception for non-Laravel PHP prototypes or internal services with simple auth needs and a documented exit plan. Do not use it for SSO, MFA, compliance-sensitive, or high-scale customer identity without a formal security review.
Decision framing: The choice is not “use this package everywhere”; it is “use the smallest reasonable auth solution for low-risk PHP contexts, and use Laravel-native or managed identity where integration, compliance, and long-term maintainability matter.”
