Relock's authentication system has a decisive advantage over other methods: its continuous, ephemeral nature. Every request carries fresh, device- and origin-bound cryptographic proof with built-in reuse and compromise detection, eliminating the weaknesses of bearer authentication (passwords, OTPs, session cookies, bearer tokens).

Whereas today's strongest authentication methods — passkeys and hardware keys — excel at protecting the private key, Relock protects the server–device relationship itself, ensuring there are no reusable credentials for an attacker to walk away with.

At its core, Relock shifts security assurance level from a one-time login event to a model of continuous cryptographic trust, delivering strong posture, phishing resistance, and regulatory alignment — all while remaining invisible and frictionless for users.
