Passkeys explained: the password's long-overdue replacement
No more reused passwords, no more phishing. How passkeys actually work — and how to start using them today.

Passwords have been the weakest link in security for thirty years. Passkeys are the first replacement that's genuinely easier to use.
A passkey is a cryptographic key pair tied to your device and unlocked by your face, fingerprint or PIN. The private half never leaves your device, and there's nothing to type, reuse, or hand to a fake login page.
Why phishing simply stops working
Because a passkey is bound to the real site's domain, a look-alike page can't trigger it. The entire category of "trick the user into typing their password" evaporates.
Adoption is the only thing standing between us and a phishing-resistant default. The technology is ready now.
