WhatA middleware platform that enables seamless upgrade of existing WebAuthn/FIDO2 credentials to post-quantum signature schemes without forcing users through painful re-enrollment.
SignalCommenters note that WebAuthn key management already has serious usability problems, and there is no clean path to upgrade these credentials to post-quantum schemes — a gap that will become critical as the quantum timeline tightens.
Why NowWebAuthn adoption has reached critical mass with passkeys rolling out across Apple, Google, and Microsoft ecosystems, but all existing credentials use classical crypto with no upgrade mechanism defined in the spec.
MarketIdentity providers, large consumer platforms, and enterprises using FIDO2 for authentication; TAM tied to the $15B+ IAM market. Current passkey providers (1Password, Dashlane, platform vendors) have no PQ upgrade story.
MoatBecoming the standard migration path for billions of existing WebAuthn credentials creates network effects — the more relying parties that integrate, the more valuable the upgrade infrastructure becomes.
