Device-bound Passkeys __top__ -

These keys are forged inside a single piece of hardware—your YubiKey, your Pixel’s secure chip, or your Mac’s Secure Enclave—and they never leave . Not for backup. Not for sync. Not for a friendly "hey, share this with your tablet."

But for the first time in decades, we have a tool that truly eliminates remote credential theft. Not reduces it. Eliminates it. device-bound passkeys

Yes, losing the device becomes a bigger deal. (Backup codes or a second hardware key solve that.) And yes, it’s slightly less convenient than cloud sync. These keys are forged inside a single piece

That world is here. They’re called .

You’ve probably heard of passkeys: the shiny new "password killer" from Apple, Google, and Microsoft. Most are synced passkeys—they float across your devices via the cloud. Convenient? Yes. But they share a subtle weakness: a sophisticated attacker who compromises your iCloud or Google account could potentially clone those keys from afar. Not for a friendly "hey, share this with your tablet

They are bound to that device by physics and cryptography.
