Alternative Tools
Other options worth considering
Drop-in auth for React and Next.js. Pre-built UI components handle sign-up, sign-in, MFA, organizations, and user profiles. The fastest path to production auth — ship in under an hour.
Open-source auth for Next.js supporting 50+ OAuth providers, JWT sessions, and database adapters. Flexible but configuration-heavy. ⚠️ Commit frequency has dropped — worth monitoring.

Common usage patterns
Protected API route
Protect a Next.js API route
import { withApiAuthRequired, getSession } from '@auth0/nextjs-auth0';
export default withApiAuthRequired(async (req, res) => {
const { user } = await getSession(req, res);
res.json({ message: `Hello ${user.name}` });
});Role-based access
Check user roles from the token
const { user } = await getSession(req, res);
const roles = user['https://myapp.com/roles'] ?? [];
if (!roles.includes('admin')) {
return res.status(403).json({ error: 'Forbidden' });
