Why I Love FIDO 2FA

Hardware = Trust

FIDO keys like Yubikey or SoloKey turn your identity into a physical object.

  • No more phishing
  • No SMS hijacks
  • No clipboard leaks

Authentication is a cryptographic challenge between the key and the site — not a shared secret.

Passwordless = No Attack Surface

FIDO2 supports full passwordless login:

navigator.credentials.get({ publicKey: { ... } })

Your private key never leaves the device. No password to brute-force. No database to breach.

Sovereign Identity

You can build your own auth stack:

  • Self-hosted WebAuthn
  • Use a FIDO key with your Meteor app
  • Map keys to wallets, DIDs, or even SSH

Your fingerprint/touch isn’t stored anywhere — it just unlocks a local keypair.

Example: SSH with FIDO

ssh-keygen -t ed25519-sk -C "sovereign@auth"

You’ll be asked to touch your FIDO2 key. Boom — hardware-backed SSH.

Universal, Yet Local

FIDO is supported by:

  • All major browsers
  • WebAuthn spec (w3c)
  • Every serious platform

Yet it lives in your pocket. Sovereign access, anywhere.

My FIDO key is my passport to the digital world — but I hold the keys, not some server.
