What the current evidence supports

Human editorial judgment · 2026-07-21

Proceed with caution

Why
Yubico itself draws the line: the CTAP 2.3 transport/UX layer is GA and shipping to all non-regulated product lines today, but the headline new capability this candidate is named for — ARKG-based hardware authorization/signing — is documented by Yubico as experimental beta with no production or long-term-support guarantee, and is unavailable on FIPS/CCN-certified keys.
Next
Pilot the GA CTAP 2.3 baseline now (PPUAT autofill UX, 16-RPID enterprise attestation, Conditional Mediation) since that portion is shipping and stable; hold ARKG/previewSign-based signing out of production checkout, custody, or compliance-sensitive flows until Yubico exits developer preview and FIPS/CCN parity lands.
