Unlock with a Touch.
No Password Typing.
Locksy now supports WebAuthn / FIDO2 biometric authentication — use your fingerprint, face, or security key to unlock protected tabs instantly. Your biometric data never leaves your device.
Tab Locked
Use your biometric or master password
No real biometric data used · Simulated demo
Zero Biometric Data Stored
Your fingerprint or face scan never leaves your device — not even to our servers. WebAuthn keeps everything local.
W3C WebAuthn / FIDO2 Standard
Built on the open web standard trusted by Google, Apple, and Microsoft. No proprietary lock-in.
Phishing-Resistant by Design
Credentials are cryptographically bound to the Locksy origin — they simply cannot be replayed on a fake site.
Fallback to Master Password
Biometrics are a convenience layer. Your master password is always the backup if hardware is unavailable.
Works with Your Device's Built-In Security
No external hardware required. Locksy leverages the authenticator already in your laptop, phone, or security key.
