Passkeys Debugger guides

Test what is hard to test with passkeys

Each guide opens the debugger with the right options already set. You run a real ceremony on your device and read what the authenticator returned.

Security key test
Create a passkey on a YubiKey, Titan Key or any FIDO2 key and check user verification, transports, firmware and FIDO certification.

Platform authenticator test
Create a passkey with Face ID, Touch ID, Windows Hello or Android and see the provider and whether the passkey is synced or device-bound.
