Authentication & Authorization Patterns
Master authentication and authorization patterns including JWT, OAuth2, session management, and RBAC to build secure, scalable access control systems.
Description
USE WHEN: Implementing user authentication systems Securing REST or GraphQL APIs Adding OAuth2/social login or SSO Designing session management Implementing RBAC or permission systems Debugging authentication issues DON'T USE WHEN: Only need UI/login page styling Task is infrastructure-only without identity concerns Cannot change auth policies

Generate Tokens
import jwt from 'jsonwebtoken'; function generateTokens(user: User) { const accessToken = jwt.sign( { userId: user.id, email: user.email, role: user.role }, process.env.JWT_SECRET!, { expiresIn: '15m' } // Short-lived ); const refreshToken = jwt.sign( { userId: user.id }, process.env.JWT_REFRESH_SECRET!, { expiresIn: '7d' } // Long-lived ); return { accessToken, refreshToken }; }
Verify Middleware
function authenticate(req: Request, res: Response, next: NextFunction) { const authHeader = req.headers.authorization; if (!authHeader?.startsWith('Bearer ')) { return res.status(401).json({ error: 'No token provided' }); } const token = authHeader.substring(7); try { const payload = jwt.verify(token, process.env.JWT_SECRET!); req.user = payload; next(); } catch (error) { return res.status(401).json({ error: 'Invalid token' }); } }
Refresh Token Flow
app.post('/api/auth/refresh', async (req, res) => { const { refreshToken } = req.body; try { // Verify refresh token const payload = jwt.verify(refreshToken, process.env.JWT_REFRESH_SECRET!); // Check if token exists in database (not revoked) const storedToken = await db.refreshTokens.findOne({ token: await hash(refreshToken), expiresAt: { $gt: new Date() } }); if (!storedToken) { return res.status(403).json({ error: 'Token revoked' }); } // Generate new access token const user = await db.users.findById(payload.userId); const accessToken = jwt.sign( { userId: user.id, email: user.email, role: user.role }, process.env.JWT_SECRET!, { expiresIn: '15m' } ); res.json({ accessToken }); } catch { res.status(401).json({ error: 'Invalid refresh token' }); } });
Session-Based Authentication
import session from 'express-session'; import RedisStore from 'connect-redis'; app.use(session({ store: new RedisStore({ client: redisClient }), secret: process.env.SESSION_SECRET!, resave: false, saveUninitialized: false, cookie: { secure: process.env.NODE_ENV === 'production', // HTTPS only httpOnly: true, // No JavaScript access maxAge: 24 * 60 * 60 * 1000, // 24 hours sameSite: 'strict' // CSRF protection } })); // Login app.post('/api/auth/login', async (req, res) => { const { email, password } = req.body; const user = await db.users.findOne({ email }); if (!user || !(await verifyPassword(password, user.passwordHash))) { return res.status(401).json({ error: 'Invalid credentials' }); } req.session.userId = user.id; req.session.role = user.role; res.json({ user: { id: user.id, email: user.email } }); }); // Logout app.post('/api/auth/logout', (req, res) => { req.session.destroy(() => { res.clearCookie('connect.sid'); res.json({ message: 'Logged out' }); }); });
OAuth2 / Social Login
import passport from 'passport'; import { Strategy as GoogleStrategy } from 'passport-google-oauth20'; passport.use(new GoogleStrategy({ clientID: process.env.GOOGLE_CLIENT_ID!, clientSecret: process.env.GOOGLE_CLIENT_SECRET!, callbackURL: '/api/auth/google/callback' }, async (accessToken, refreshToken, profile, done) => { // Find or create user let user = await db.users.findOne({ googleId: profile.id }); if (!user) { user = await db.users.create({ googleId: profile.id, email: profile.emails?.[0]?.value, name: profile.displayName }); } return done(null, user); })); // Routes app.get('/api/auth/google', passport.authenticate('google', { scope: ['profile', 'email'] })); app.get('/api/auth/google/callback', passport.authenticate('google', { session: false }), (req, res) => { const tokens = generateTokens(req.user); res.redirect(`${FRONTEND_URL}/auth/callback?token=${tokens.accessToken}`); });
Authorization: RBAC
enum Role { USER = 'user', MODERATOR = 'moderator', ADMIN = 'admin' } const roleHierarchy: Record<Role, Role[]> = { [Role.ADMIN]: [Role.ADMIN, Role.MODERATOR, Role.USER], [Role.MODERATOR]: [Role.MODERATOR, Role.USER], [Role.USER]: [Role.USER] }; function hasRole(userRole: Role, requiredRole: Role): boolean { return roleHierarchy[userRole].includes(requiredRole); } function requireRole(...roles: Role[]) { return (req: Request, res: Response, next: NextFunction) => { if (!req.user) { return res.status(401).json({ error: 'Not authenticated' }); } if (!roles.some(role => hasRole(req.user.role, role))) { return res.status(403).json({ error: 'Insufficient permissions' }); } next(); }; } // Usage app.delete('/api/users/:id', authenticate, requireRole(Role.ADMIN), async (req, res) => { await db.users.delete(req.params.id); res.json({ message: 'User deleted' }); } );
Permission-Based Access
enum Permission { READ_USERS = 'read:users', WRITE_USERS = 'write:users', DELETE_USERS = 'delete:users', READ_POSTS = 'read:posts', WRITE_POSTS = 'write:posts' } const rolePermissions: Record<Role, Permission[]> = { [Role.USER]: [Permission.READ_POSTS, Permission.WRITE_POSTS], [Role.MODERATOR]: [Permission.READ_POSTS, Permission.WRITE_POSTS, Permission.READ_USERS], [Role.ADMIN]: Object.values(Permission) }; function requirePermission(...permissions: Permission[]) { return (req: Request, res: Response, next: NextFunction) => { if (!req.user) return res.status(401).json({ error: 'Not authenticated' }); const hasAll = permissions.every(p => rolePermissions[req.user.role]?.includes(p) ); if (!hasAll) return res.status(403).json({ error: 'Insufficient permissions' }); next(); }; }
Resource Ownership
function requireOwnership(resourceType: 'post' | 'comment') { return async (req: Request, res: Response, next: NextFunction) => { if (!req.user) return res.status(401).json({ error: 'Not authenticated' }); // Admins can access anything if (req.user.role === Role.ADMIN) return next(); const resource = await db[resourceType].findById(req.params.id); if (!resource) return res.status(404).json({ error: 'Not found' }); if (resource.userId !== req.user.userId) { return res.status(403).json({ error: 'Not authorized' }); } next(); }; } // Usage: Users can only update their own posts app.put('/api/posts/:id', authenticate, requireOwnership('post'), updatePost);
Password Security
import bcrypt from 'bcrypt'; import { z } from 'zod'; const passwordSchema = z.string() .min(12, 'Password must be at least 12 characters') .regex(/[A-Z]/, 'Must contain uppercase') .regex(/[a-z]/, 'Must contain lowercase') .regex(/[0-9]/, 'Must contain number') .regex(/[^A-Za-z0-9]/, 'Must contain special character'); async function hashPassword(password: string): Promise<string> { return bcrypt.hash(password, 12); // 12 rounds } async function verifyPassword(password: string, hash: string): Promise<boolean> { return bcrypt.compare(password, hash); }
โ Do
Use HTTPS everywhere Hash passwords with bcrypt (12+ rounds) Use short-lived access tokens (15-30 min) Store refresh tokens in database (revocable) Validate all input Rate limit auth endpoints Log security events Use secure cookie flags (httpOnly, secure, sameSite)
โ Don't
Store passwords in plain text Store JWT in localStorage (XSS vulnerable) Use weak JWT secrets Trust client-side auth checks only Expose stack traces in errors Skip server-side validation Ignore rate limiting
Common Pitfalls
IssueSolutionJWT in localStorageUse httpOnly cookiesNo token expirationSet short TTL + refresh tokensWeak passwordsEnforce strong policy with zodNo rate limitingUse express-rate-limit + RedisClient-only authAlways validate server-side
