Virtual FIDO is a software-emulated FIDO2/U2F USB security key (like a YubiKey) that attaches to the host via a USB/IP server over local TCP. It supports 2FA and WebAuthN logins, storing credentials encrypted with a passphrase and using a terminal-based approval mechanism.

Use cases

• test webauthn flows without a hardware yubikey
• emulate a fido2 usb security key on linux
• use 2fa on sites requiring a hardware token when i don't have one
• develop and debug ctap/fido2 client software
• store passkey credentials in an encrypted local file
• simulate a u2f device for automated testing

When to choose

• you need a FIDO2/U2F device for testing or 2FA but lack physical hardware
• you're on Windows or Linux and want a software security key
• you're developing WebAuthN/CTAP integrations and need a controllable token

When to avoid

• you need real hardware-backed security for production accounts
• you're on macOS (not yet supported)
• you need a polished, stable tool - the project is beta with changing APIs
