Why passkeys win

Passwords are the breach vector
81% of data breaches start with stolen or weak credentials. Passkeys eliminate the attack surface entirely — there is nothing to steal.
One tap, fully verified
Biometric authentication completes in under 200ms. No typing, no remembering, no password reset emails sent at 2am.
Phishing becomes structurally impossible
Passkeys are cryptographically bound to the origin domain. No fake login page, no matter how convincing, can capture them.
Your users already carry the hardware
Over six billion passkey-ready devices ship this year — phones, laptops, and tablets. The infrastructure adoption problem is already solved.
