SkinID wot Quentin Nallet

SkinID turns your NFC implant into the only password you'll ever need.

Sign in to any website with a tap of your hand. SkinID autofills your saved passwords and silently signs your saved passkey (FIDO2/WebAuthn) challenges — your hardware identity replaces typing, masters passwords, and 2FA codes.

How it works
• On any login page, tap the SkinID button (or click "Sign in with passkey")
• Hold your hand to the back of your phone — your implant is read
• Credentials fill in. You're in.

Privacy
• Credentials encrypted server-side with a key derived from your implant
• Your implant UID is never shared with the websites you sign into
• No browsing or page content collected — the extension only acts on the page you sign in to

Requirements
• A SkinID account at skinid.ch
• An xNT or xDF3 NFC implant (or any NTAG216 / DESFire EV3 tag for testing)
• The SkinID Android app (link from skinid.ch) for the implant scan flow on Firefox Android
