What is zerofido?

ZeroFIDO turns a Flipper Zero into a passkey and security key app supporting WebAuthn, FIDO2, U2F, Client PIN, USB HID for desktops, and NFC for phones. Plug it into your Windows PC via USB for Firefox passkey security key flows or tap to an iPhone for GitHub passkey login/registration—handling everything from "insert your security key into the USB port" prompts to mobile passkey GitHub Android/iPhone use. Written in C, it stores discoverable credentials on-device with local approval.

Why is it gaining traction?

It bridges passkey vs FIDO2 security key, passkey vs security key Google/Microsoft gaps on a hacker gadget cheaper than YubiKeys, passing FIDO conformance tests for U2F/FIDO2.0 (2.1 experimental). Developers dig the host tools for probing CTAP/HID/NFC, exporting cert metadata, and GitHub passkey nickname/registration flows without buying dedicated hardware.

Who should use this?

Flipper Zero owners testing passkeys GitHub or Google passkey and security key setups on Windows/mobile. Security researchers simulating "passkey registration failed" or passkey security key USB attacks. Pentesters needing portable FIDO2 for Firefox passkey security key validation.

Verdict

Grab the FAP for fun Flipper passkey experiments—10 stars and 1.0% credibility score scream experimental, but solid docs, conformance testing, and warnings to keep backups make it viable for tinkerers. Skip for production logins.
