Introduction
Starting October 2027 and ending November 2027, we will retire the isAttestationEnforced and keyRestrictionsproperties from the existing fido2AuthenticationMethodConfiguration API schema. This change aligns with the latest update to the passkey policy API schema, which introduces support for granular group-based configurations with passkey profiles.
During the retirement period, isAttestationEnforced and keyRestrictions will remain in sync with their counterparts attestationEnforcement and keyRestrictions within the Default passkey profile.

Retirement begins in mid-October 2027 and is expected to complete by early November 2027.
