YubiKey
A hardware security key produced by Yubico that supports multiple authentication protocols, including FIDO2 and WebAuthn. It provides strong two-factor or passwordless authentication in an offline, physical form factor, enabling users to authenticate without relying solely on software-based credentials.

Anti-phishing MFA (such as FIDO2/WebAuthn hardware keys or platform passkeys) can resist real-time phishing and man-in-the-middle attacks, because authentication is bound to the origin of the specific website, and a phishing domain cannot obtain a valid signed challenge response.
CTAP2 defines the communication between authenticators and client devices, and is responsible for enabling external hardware keys (such as YubiKey) or platform built-in authenticators to work together with operating systems and browsers.
Accessing Daybreak Blue requires a paid plan, advanced account security, a registered physical FIDO2 key (such as a YubiKey), identity verification with a selfie and ID at chatgpt.com/cyber along with a stated purpose, and OpenAI reviews each case individually and has the right to refuse.
MFA requires users to provide an additional second verification factor when logging in, such as TOTP, a hardware security key, or biometrics.
Common forms of multi-factor authentication (MFA) include SMS verification codes, time-based one-time password apps (such as Google Authenticator), hardware security keys (such as YubiKey), and biometric identification
