QuantumAuth is an open-source, hardware-anchored, post-quantum authentication platform.
This monorepo contains the official SDKs used to integrate QuantumAuth into web and server-side applications.
QuantumAuth delivers device-bound identity using TPM modules, Secure Enclave, and post-quantum signatures — creating an authentication system that is invisible to users, impossible to phish, and resistant to next-generation threats.
Client-side SDK for browsers and frameworks like Next.js.
Server-side SDK for Node.js.
