OpenAI introduced Advanced Account Security on April 30, an opt-in program targeting high-risk users — journalists, researchers, political dissidents — that requires two passkeys or hardware security keys to log in and permanently disables password-based recovery. Custom co-branded YubiKeys (a C NFC and a C Nano) are sold as a $68 two-pack, roughly half the retail price of comparable hardware. OpenAI's CISO framed the move as extending internally used protections to the broader user base; Yubico's CEO described it as "a new model for phishing-resistant security at scale for the AI ecosystem."
