authID has upgraded its PrivacyKey biometric digital signature platform to support three NIST-standardized post-quantum cryptographic algorithms: ML-DSA-65, SLH-DSA-128s, and SLH-DSA-256s. The addition spans two independent mathematical foundations, lattice-based cryptography through ML-DSA and hash-based cryptography through SLH-DSA, giving organizations the ability to select algorithms per operation, per policy, or per risk model rather than relying on a single cryptographic approach.
The company describes the upgrade as the industry’s first biometric authentication solution purpose-built to withstand quantum computing threats. PrivacyKey’s architecture stores no biometric data at rest. Each authentication event regenerates an ephemeral cryptographic keypair from a live biometric presentation, signs the transaction, and immediately destroys the private key. Each PrivacyKeyMap, authID’s encrypted biometric guidance artifact, is protected by a unique AES-256 key that is sharded across multiple independent nodes in separate trust domains using a threshold multi-party computation (MPC) ceremony, ensuring no single node can reconstruct the key.
“The quantum era is not a distant threat; it’s an engineering reality today,” said Rhon Daguro, CEO of authID. “NIST has finalized its standards, regulatory timelines are accelerating, and organizations that rely on legacy biometric architectures are already running out of time. We built PrivacyKey from the ground up on a zero-storage, ephemeral-key foundation precisely because we knew this day was coming.”
The post-quantum upgrade extends the PrivacyKey zero-storage biometric platform authID launched in January 2025, which was designed from the outset to avoid retaining biometric data at rest. Since launch, the platform has achieved commercial scale: PrivacyKey reported 472 percent biometric enrollment growth at a major global retailer in Q4 2025, underlining the deployment base now receiving post-quantum hardening.
authID has also been expanding into government verticals through its PIV-aligned biometric security package for critical infrastructure, the sector facing the most urgent post-quantum migration timelines under current federal guidance. The quantum-resistant PrivacyKey platform is available now for enterprise customers across banking, finance, compliance, government, and healthcare. NIST finalized the ML-DSA standard under FIPS 204 and SLH-DSA under FIPS 205 in August 2024, triggering enterprise migration timelines that authID’s announcement is directly targeting.
