Replace CAPTCHA and SMS with server-verified passkeys

4 followers

Bot-prevention API using WebAuthn passkeys and security keys. Your backend creates a verification flow, the user approves on their own device, and your server redeems a single-use result. No CAPTCHA, no SMS codes, no raw biometric data stored. It raises the cost of automated abuse. It does not prove identity or liveness.
