Availability is not adoption. Watch the sign-in.

FIDO Alliance's 2026 Passkey Index reports that passkeys accounted for 36% of successful sign-ins in its contributing organisations. Its executive summary also reports a 93% success rate for passkey sign-ins, compared with 78% for traditional multifactor authentication, and shorter sign-in times. These are observations from the index participants, not measurements of every online service or a guarantee for a particular deployment.

Editorial interpretation: follow the whole authentication funnel: eligibility, enrolment, successful use and recovery. A strong enrolment figure can hide a weak everyday experience. Keep recovery abuse and fallback behaviour visible when assessing whether an authentication change improves both security and usability.
