Use when implementing auth, API authorization, token management. Follows RFC 9700 (2025).\n---\n# Auth Security\n\n## Core Principles\n\n- **OAuth 2.1** — Follow RFC 9700 (January 2025)\n- **PKCE Required** — All clients must use PKCE\n- **Short-lived Tokens** — Access tokens expire in 5-15 minutes\n- **Token Rotation** — Refresh tokens are single-use\n- **HttpOnly Storage** — Browser tokens in HttpOnly cookies\n- **Explicit Algorithm** — Never trust JWT header algorithm\n- **No backwards compatibility** — Delete deprecated auth flows\n\n---\n\n## OAuth 2.1 Key Changes\n\n### Deprecated Flows (DO NOT USE)\n\n| Flow | Status | Replacement |\n|------|--------|-------------|\n| Implicit Grant | Removed | Authorization Code + PKCE |\n| Password Grant | Removed | Authorization Code + PKCE |\n| Auth Code without PKCE | Removed | Must use PKCE |\n\n### Required: Authorization Code + PKCE\n\n```typescript\nimport crypto from 'crypto';\n\n// 1. Generate code verifier (43-128 chars)\nfunction generateCodeVerifier(): string {\n return crypto.randomBytes(32).toString('base64url');\n}\n\n// 2. Generate code challenge\nfunction generateCodeChallenge(verifier: string): string {\n return crypto\n .createHash('sha256')\n .update(verifier)\n .digest('base64url');\n}\n\n// 3. Authorization request\nconst verifier = generateCodeVerifier();\nconst challenge = generateCodeChallenge(verifier);\n\nconst authUrl = new URL('https://auth.example.com/authorize');\nauthUrl.searchParams.set('response_type', 'code');\nauthUrl.searchParams.set('client_id', CLIENT_ID);\nauthUrl.searchParams.set('redirect_uri', REDIRECT_URI);\nauthUrl.searchParams.set('code_challenge', challenge);\nauthUrl.searchParams.set('code_challenge_method', 'S256');\nauthUrl.searchParams.set('scope', 'openid profile email');\nauthUrl.searchParams.set('state', generateState());\n\n// 4. Token exchange (after redirect)\nconst tokenResponse = await fetch('https://auth.example.com/token', {\n method: 'POST',\n headers: { 'Content-Type': 'application/x-www-form-urlencoded' },\n body: new URLSearchParams({\n grant_type: 'authorization_code',\n code: authorizationCode,\n redirect_uri: REDIRECT_URI,\n client_id: CLIENT_ID,\n code_verifier: verifier, // Prove we initiated the request\n }),\n});\n```\n\n---\n\n## JWT Best Practices\n\n### Algorithm Selection (2025)\n\n| Priority | Algorithm | Notes |\n|----------|-----------|-------|\n| 1 | EdDSA (Ed25519) | Most secure, quantum-resistant properties |\n| 2 | ES256 (ECDSA P-256) | Widely supported, compact signatures |\n| 3 | PS256 (RSA-PSS) | More secure than RS256 |\n| 4 | RS256 (RSA PKCS#1) | Best compatibility |\n\n```typescript\n// Recommended: ES256\nimport { SignJWT, jwtVerify } from 'jose';\n\nconst privateKey = await importPKCS8(PRIVATE_KEY_PEM, 'ES256');\nconst publicKey = await importSPKI(PUBLIC_KEY_PEM, 'ES256');\n\n// Sign\nconst token = await new SignJWT({ sub: userId, scope: 'read write' })\n .setProtectedHeader({ alg: 'ES256', typ: 'JWT', kid: keyId })\n .setIssuer('https://auth.example.com')\n .setAudience('https://api.example.com')\n .setExpirationTime('15m')\n .setIssuedAt()\n .setJti(crypto.randomUUID())\n .sign(privateKey);\n```\n\n### Token Structure\n\n```typescript\ninterface AccessTokenPayload {\n // Standard claims\n iss: string; // Issuer\n sub: string; // Subject (user ID)\n aud: string; // Audience\n exp: number; // Expiration (Unix timestamp)\n iat: number; // Issued at\n jti: string; // JWT ID (unique identifier)\n\n // Custom claims\n scope: string; // Permissions\n email?: string; // User email\n roles?: string[]; // User roles\n}\n```\n\n### Verification (Critical)\n\n```typescript\nimport { jwtVerify, errors } from 'jose';\n\nasync function verifyAccessToken(token: string): Promise {\n try {\n const { payload } = await jwtVerify(token, publicKey, {\n // CRITICAL: Explicitly specify allowed algorithms\n algorithms: ['ES256'],\n\n // Validate standard claims\n issuer: 'https://auth.example.com',\n audience: 'https://api.example.com',\n\n // Clock tolerance for sync issues\n clockTolerance: 30,\n });\n\n // Additional validation\n if (!payload.scope?.includes('read')) {\n throw new Error('Insufficient scope');\n }\n\n return payload as AccessTokenPayload;\n } catch (err) {\n if (err instanceof errors.JWTExpired) {\n throw new AuthError('Token expired', 'TOKEN_EXPIRED');\n }\n if (err instanceof errors.JWTClaimValidationFailed) {\n throw new AuthError('Invalid token claims', 'INVALID_CLAIMS');\n }\n throw new AuthError('Invalid token', 'INVALID_TOKEN');\n }\n}\n```\n\n---\n\n## Token Storage\n\n### Web Applications\n\n```typescript\n// Set token in HttpOnly cookie (server-side)\nfunction setAuthCookie(res: Response, token: string) {\n res.cookie('access_token', token, {\n httpOnly: true, // Not accessible via JavaScript\n secure: true, // HTTPS only\n sameSite: 'strict', // CSRF protection\n maxAge: 15 * 60 * 1000, // 15 minutes\n path: '/api', // Only sent to API routes\n });\n}\n\n// Refresh token (longer-lived)\nfunction setRefreshCookie(res: Response, token: string) {\n res.cookie('refresh_token', token, {\n httpOnly: true,\n secure: true,\n sameSite: 'strict',\n maxAge: 7 * 24 * 60 * 60 * 1000, // 7 days\n path: '/api/auth/refresh', // Only for refresh endpoint\n });\n}\n```\n\n### Single Page Applications (SPA)\n\n```typescript\n// Store in memory (NOT localStorage/sessionStorage)\nclass TokenManager {\n private accessToken: string | null = null;\n\n setToken(token: string) {\n this.accessToken = token;\n }\n\n getToken(): string | null {\n return this.accessToken;\n }\n\n clearToken() {\n this.accessToken = null;\n }\n}\n\n// Use with Refresh Token Rotation\n// Refresh token in HttpOnly cookie\n// Access token in memory\n```\n\n### Storage Comparison\n\n| Storage | XSS Safe | CSRF Safe | Persistence |\n|---------|----------|-----------|-------------|\n| HttpOnly Cookie | Yes | Needs SameSite | Yes |\n| Memory | Yes | Yes | No (lost on reload) |\n| localStorage | No | Yes | Yes |\n| sessionStorage | No | Yes | Tab only |\n\n---\n\n## Refresh Token Rotation\n\n### Flow\n\n```\n1. Client sends refresh_token\n2. Server validates refresh_token\n3. Server generates NEW access_token + NEW refresh_token\n4. Server INVALIDATES old refresh_token\n5. Server returns new tokens\n6. Client stores new tokens\n```\n\n### Implementation\n\n```typescript\nasync function refreshTokens(refreshToken: string) {\n // Find token in database\n const stored = await db.refreshToken.findUnique({\n where: { token: hashToken(refreshToken) },\n include: { user: true },\n });\n\n if (!stored) {\n throw new AuthError('Invalid refresh token', 'INVALID_TOKEN');\n }\n\n // Check if already used (reuse detection)\n if (stored.usedAt) {\n // Potential token theft - revoke ALL user tokens\n await db.refreshToken.deleteMany({\n where: { userId: stored.userId },\n });\n\n // Alert security team\n await alertSecurityTeam({\n event: 'REFRESH_TOKEN_REUSE',\n userId: stored.userId,\n tokenId: stored.id,\n });\n\n throw new AuthError('Token reuse detected', 'TOKEN_REUSE');\n }\n\n // Check expiration\n if (stored.expiresAt < new Date()) {\n throw new AuthError('Refresh token expired', 'TOKEN_EXPIRED');\n }\n\n // Mark as used (but keep for reuse detection)\n await db.refreshToken.update({\n where: { id: stored.id },\n data: { usedAt: new Date() },\n });\n\n // Generate new tokens\n const newAccessToken = await generateAccessToken(stored.user);\n const newRefreshToken = await generateRefreshToken(stored.user);\n\n // Store new refresh token\n await db.refreshToken.create({\n data: {\n token: hashToken(newRefreshToken),\n userId: stored.userId,\n expiresAt: addDays(new Date(), 7),\n previousTokenId: stored.id, // Chain for audit\n },\n });\n\n return {\n accessToken: newAccessToken,\n refreshToken: newRefreshToken,\n };\n}\n```\n\n---\n\n## Attack Prevention\n\n### Algorithm Confusion\n\n```typescript\n// WRONG: Trusts header algorithm\njwt.verify(token, key); // Uses alg from header\n\n// CORRECT: Explicit algorithm\njwt.verify(token, key, { algorithms: ['ES256'] });\n```\n\n### CSRF Protection\n\n```typescript\n// Use SameSite cookies\nres.cookie('session', token, {\n sameSite: 'strict', // or 'lax' for cross-site links\n});\n\n// Or double-submit cookie pattern\nconst csrfToken = crypto.randomBytes(32).toString('hex');\nres.cookie('csrf', csrfToken, { httpOnly: false });\n// Client sends csrf token in header\n```\n\n### XSS Protection\n\n```typescript\n// Content Security Policy\nres.setHeader('Content-Security-Policy', [\n \"default-src 'self'\",\n \"script-src 'self'\",\n \"style-src 'self' 'unsafe-inline'\",\n].join('; '));\n\n// Use HttpOnly cookies for tokens\n// Never store tokens in localStorage\n```\n\n### Token Binding (DPoP)\n\n```typescript\n// Demonstration of Proof of Possession\n// Bind token to client's key pair\n\nconst dpopProof = await new SignJWT({\n htm: 'POST',\n htu: 'https://api.example.com/resource',\n ath: await hashAccessToken(accessToken), // Access token hash\n})\n .setProtectedHeader({ alg: 'ES256', typ: 'dpop+jwt', jwk: publicKey })\n .setJti(crypto.randomUUID())\n .setIssuedAt()\n .sign(privateKey);\n\n// Send with request\nfetch('https://api.example.com/resource', {\n headers: {\n Authorization: `DPoP ${accessToken}`,\n DPoP: dpopProof,\n },\n});\n```\n\n---\n\n## Token Revocation\n\n```typescript\n// Revoke all user tokens (e.g., password change, logout all)\nasync function revokeAllUserTokens(userId: string) {\n await db.refreshToken.deleteMany({\n where: { userId },\n });\n\n // If using token blacklist for access tokens\n await redis.sadd(`revoked:${userId}`, Date.now());\n await redis.expire(`revoked:${userId}`, 15 * 60); // 15 min (access token lifetime)\n}\n\n// Check blacklist during verification\nasync function isTokenRevoked(userId: string, iat: number): Promise {\n const revokedAt = await redis.get(`revoked:${userId}`);\n return revokedAt && parseInt(revokedAt) > iat * 1000;\n}\n```\n\n---\n\n## Checklist\n\n```markdown\n## OAuth 2.1\n- [ ] Using Authorization Code flow\n- [ ] PKCE enabled for all clients\n- [ ] No implicit or password grants\n- [ ] Redirect URI exact matching\n\n## JWT\n- [ ] Using ES256 or EdDSA algorithm\n- [ ] Explicit algorithm verification\n- [ ] Short expiration (≤15 min)\n- [ ] Unique jti for each token\n- [ ] Issuer and audience validation\n\n## Tokens\n- [ ] HttpOnly cookies for web apps\n- [ ] Refresh token rotation enabled\n- [ ] Reuse detection implemented\n- [ ] Token revocation mechanism\n\n## Security\n- [ ] HTTPS everywhere\n- [ ] SameSite cookies\n- [ ] CSP headers configured\n- [ ] Rate limiting on auth endpoints\n- [ ] Brute force protection\n```\n\n---\n\n## See Also\n\n- [reference/oauth2.1.md](reference/oauth2.1.md) — OAuth 2.1 deep dive\n- [reference/jwt.md](reference/jwt.md) — JWT patterns\n- [reference/attacks.md](reference/attacks.md) — Attack prevention\n- [templates/typescript/auth.service.ts](templates/typescript/auth.service.ts) — TypeScript auth service starter\n","tagline":"OAuth 2.1 + JWT authentication security best practices.
