Authentication patterns: session vs JWT vs OAuth comparison, provider selection (NextAuth, Clerk, Supabase Auth), security checklist, and common mistakes. Use when implementing auth, reviewing auth flows, or choosing auth providers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Authentication Patterns Skill Reference for implementing secure, production-ready authentication. ## WHEN_TO_USE Apply this skill when implementing authentication in a project, reviewing existing auth flows for security issues, choosing between auth providers, or migrating between auth strategies. Use the security checklist before shipping any auth-related change. ## AUTH_APPROACHES | Approach | How It Works | Best For | Drawbacks | |----------|-------------|----------|-----------| | Session-based | Server stores session in DB/Redis, client holds session ID cookie | Traditional server-rendered apps, apps needing instant revocation | Requires server-side storage, harder to scale horizontally without shared store | | JWT (stateless) | Server signs token, client sends it on each request | API-first apps, microservices, mobile clients | Cannot revoke without blocklist, token size grows with claims | | OAuth 2.0 / OIDC | Delegates auth to external provider (Google, GitHub, etc.) | Social login, enterprise SSO, reducing auth responsibility | More complex flow, depends on external provider availability | …

How to install
mdr add zebbern/claude-code-guide/authentication-patterns@sha256:4c26152037ad2826The line at the top of this page pins the label git:20260531.164971d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
