Using a Security key with Gmail

A clear, concise guide on using a hardware Security Key1 with a Gmail account. I didn’t even know it was possible to avoid using SMS as your backup second factor – thanks to this guide I have my Key as my main and the Authenticator app as backup. No SMS involved. (My phone number has since been removed from my Google account)

The official documentation/setup guide should really make this clearer.

  1. I use this simple FIDO/U2F key by Yubico (affiliate link) which is the key recommended in the guide.
