## Bio

John Bradley is senior standards architect at Yubico and one of the few people whose name appears across both the federation and the authenticator halves of modern identity: [OpenID Connect](https://startwithidentity.com/standards/openid-connect/) and OAuth on one side, [WebAuthn and FIDO2](https://startwithidentity.com/standards/webauthn-fido2/) on the other. He was previously a senior technical architect at Ping Identity and served on the OpenID Foundation board.

## Where their work shows up

Passkeys work because the credential is bound to an origin and never leaves the authenticator, which is what makes [phishing resistance](https://startwithidentity.com/rankings/best-phishing-resistant-mfa/) a property of the protocol rather than a property of the user's attention. That guarantee lives in the WebAuthn and CTAP specifications he helped write. See the [implementing passkeys in the enterprise](https://startwithidentity.com/guides/authentication/implementing-passkeys-enterprise/) guide and [Yubico](https://startwithidentity.com/vendors/mfa/yubico/).
