Today we’re launching Advanced Account Security for ChatGPT accounts, an opt-in setting for people at increased risk of digital attacks, such as journalists and public officials, and for anyone who wants our strongest account protections. AAS requires passkeys or physical security keys, disables password-based login, tightens recovery, shortens sessions, improves session visibility, and automatically excludes conversations from model training. These protections also mean users take on more responsibility for account recovery. We’re also partnering with @Yubico to make hardware security keys easier to adopt through preferred pricing on a YubiKey bundle for eligible ChatGPT account holders. Security keys are one of the strongest defenses against phishing, and this partnership helps make them more accessible.
Ready to secure your AI journey? Big news! Today we announced we've partnered with @OpenAI to bring custom-branded 2-packs of YubiKeys to the ChatGPT ecosystem! ✅ Phishing-resistant ✅ Passwordless ✅ The gold standard for AI protection Learn more: yubico.com/press-releases…

Prof. Donald Knuth opened his new paper with "Shock! Shock!" Claude Opus 4.6 had just solved an open problem he'd been working on for weeks — a graph decomposition conjecture from The Art of Computer Programming. He named the paper "Claude's Cycles." 31 explorations. ~1 hour. Knuth read the output, wrote the formal proof, and closed with: "It seems I'll have to revise my opinions about generative AI one of these days." The man who wrote the bible of computer science just said that. In a paper named after an AI. Paper: cs.stanford.edu/~knuth/papers/…
