A post-quantum identity protocol for Web3.
QuantumAuth is an open-source identity and authorization protocol built on hardware-sealed keys, account abstraction, and post-quantum cryptography. It enables cold-wallet-grade security with hot-wallet convenience, without exposing private keys.
QuantumAuth kills the #1 cause of account hacks : stolen credentials.
Passwords are already lost: billions leaked, millions phished, and reused everywhere. QuantumAuth replaces them with device-bound cryptographic identity, cutting off the attack surface built on stolen logins.
