SkinID — NFC Implant Authentication

About

SkinID turns your NFC implant into a universal authenticator.

ONE TAP, EVERY LOGIN
Tap your hand on a USB NFC reader (or your iPhone) to fill passwords and sign in with passkeys on any website. Your credentials live encrypted on SkinID — your implant is the key.

PASSKEYS, BUILT-IN
SkinID acts as a cross-platform FIDO2/WebAuthn authenticator. Register passkeys for sites like GitHub, Adobe, Google, Amazon, and thousands of others. The same passkey works on Mac, iPhone, iPad, and Windows — no more "this passkey is locked to one device."

STRONGER THAN PASSWORDS
- AES-256-GCM encrypted credential storage
- WebAuthn-grade signatures, not shared secrets that leak
- Phishing protection: SkinID won't fill on lookalike domains
- No master password to lose, no password manager to memorize

HOW IT WORKS
1. Install the SkinID app on Mac or Windows (download at skinid.ch)
2. Pair your NFC chip via a USB reader, or via iPhone NFC
3. Save credentials at skinid.ch/management
4. Visit any login page → SkinID's button appears
5. Tap your implant → done

This Chrome extension provides the in-page experience: detects login forms, auto-fills credentials after a scan, and intercepts WebAuthn passkey requests so your implant signs the challenge.
