Lean passwordless authentication

The email field is gone. The password field is gone. The app still works—faster, safer, cleaner. This is lean passwordless authentication.

Lean passwordless authentication removes the entire password layer from your stack. No password creation. No password reset flows. No password breaches from reused credentials. Users log in with secure, ephemeral methods like magic links, passkeys, or device biometrics. The session is created in one step, without shared secrets stored on your servers.

Most passwordless systems still carry heavy complexity—extra identity providers, SDK bloat, and slow redirects. Lean passwordless authentication strips this to the minimum. The client calls your backend. The backend verifies with a lean identity API using short-lived tokens and modern cryptography. No third-party login screens. No multiple redirects. Direct, low-latency authentication with fewer points of failure.

This approach hardens security. An attacker cannot phish a password you never asked for. Token lifetimes are enforced at the protocol level. The login channel can use encrypted links sent over verified communication paths. Device keys are stored in secure enclaves, not your database. Logs hold no sensitive credential data, reducing compliance burden.

It also improves the developer experience. You integrate once with a lightweight auth endpoint. There is no account state for passwords to manage. Your product avoids friction-heavy flows for users, cutting onboarding drop-off. The auth system becomes easy to reason about: request, verify, issue session.

Lean passwordless authentication matches modern architecture patterns: API-first backends, single-page apps, and edge deployment. It scales without centralized password stores. It avoids the weakest link in most identity systems, while keeping the integration surface small.
