Auth.js (NextAuth v5) authentication patterns - configuration, providers, session strategies, middleware, database adapters, role-based access, Edge compatibility.
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
# Auth.js (NextAuth v5) Patterns
> **Quick Guide:** Configure Auth.js in a root `auth.ts` file exporting `{ auth, handlers, signIn, signOut }` from `NextAuth()`. Use the unified `auth()` function everywhere (Server Components, Route Handlers, middleware). Default session strategy is JWT (cookie-based); add a database adapter for persistent sessions. Protect routes via middleware or per-page `auth()` checks.

## CRITICAL: Before Using This Skill
**(You MUST configure Auth.js in a root `auth.ts` file and export `{ auth, handlers, signIn, signOut }` from `NextAuth()`)**
**(You MUST use the unified `auth()` function for server-side session access - NOT the deprecated `getServerSession()`, `getSession()`, or `getToken()`)**
**(You MUST use `AUTH_SECRET` environment variable - `NEXTAUTH_SECRET` is deprecated in v5)**
**(You MUST use `AUTH_` prefixed environment variables for provider credentials (e.g., `AUTH_GITHUB_ID`, `AUTH_GITHUB_SECRET`) - they are auto-detected)**
**(You MUST split auth config into `auth.config.ts` (Edge-compatible) and `auth.ts` (with adapter) when using database sessions with middleware)**

How to install
mdr add agents-inc/skills/api-auth-nextauth@sha256:9efc1f9726c12c30The line at the top of this page pins the label git:20261016.afd0e14, 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.
