I was using https://webauthn.io for testing: Attestation type: Direct Authenticator Type: Cross platform User Verification: Required Register with Resident Key: Required When I try to register, NFC gesture is ignored and key prompt is only cancellable, no matter if Client PIN is pre-installed on token or not. If I change User Verification to 'Preferred', NFC gesture is recognized and PIN is asked both during registration and authentication only if Client PIN was pre-installed on token, otherwise is never asked. 1685700 1 webkit-bug-importer 2020-09-04 09:36:21 -0700 <rdar://problem/68350577> 1688187 2 jiewen_tan 2020-09-13 23:35:01 -0700 *** This bug has been marked as a duplicate of bug 215836 ***
