Passkey Engineering — Tokyo
Engineering a passwordless future.
Sonic Ready specializes in passkeys (FIDO2 / WebAuthn). We integrate phishing-resistant, next-generation authentication into your service, from design through operations.
HOW PASSKEY WORKS ↓Protocol
Passkeys: a new way to authenticate.
Passkeys eliminate the password as a shared secret and verify identity using public-key signatures. The process works in three steps, from registration to verification.
STEP 01 — REGISTRATION
Generate a Key Pair
The user's device creates a unique key pair for each service. Only the public key is sent to the server.
private key → device (Secure Enclave)
public key → server
STEP 02 — AUTHENTICATION
Sign with Biometrics
The private key, unlocked by fingerprint or facial recognition, signs a challenge sent by the server.
challenge + origin → sign(private key)
STEP 03 — VERIFICATION
Verify with the Public Key
The server verifies the signature with the public key. No secret travels over the network or resides on the server, preventing credential leaks, stuffing attacks, and phishing.

Why Passkey
Safer and simpler than passwords.
Advanced Security
Cryptographic authentication based on biometrics and device credentials eliminates the risks of password leaks and credential stuffing.
User-Friendly
Intuitive fingerprint or facial recognition frees users from cumbersome password management and provides a seamless login experience.
Reliable Access
Cross-device coordination enables authentication from any device after a single setup, improving convenience and reducing user friction.
