Add JWT authentication to your login endpoint.

Protect every sign-in request with signed tokens, verified middleware, and a login flow your users never have to think about.

JWT middleware validates every request before it reaches your application.

The login request stops here. The risk does too.

A lightweight middleware layer verifies token signatures, rejects invalid claims, and hands trusted identity to your application.

Validate RS256 and HS256 tokens against your configured keys.

Enforce issuer, audience, expiry, and required scopes.

Pass a typed, verified user payload to the protected route.

PROTECTION / ALWAYS ON

Build once, protect every login route, and keep your team focused on the experience beyond the sign-in screen.

Add one middleware import and protect the endpoint.

Return safe unauthorized responses for missing, malformed, altered, expired, or unverifiable tokens.

Load signing keys from protected configuration and replace them without exposing application code.

Use the same policy across Express, Next.js, Fastify, and serverless routes.

Track rejected tokens and authentication events in one audit stream.

Reject valid-looking tokens when the referenced account is disabled, deleted, or no longer eligible.

IMPLEMENTATION / 02

Use the middleware at the route boundary. Invalid tokens never enter your application logic.

// Verify before the login handler runs
app.post('/login', verifyJWT, loginHandler)
