Initial checks

Start by checking that there aren't any previous ssh keys inside the FIDO2 authenticator of your YubiKey. You can check if they exist by running the command below:

nix shell nixpkgs#yubikey-manager -c ykman fido credentials list

If the command above outputs a string mentioning "ssh" or "openssh", then you have already got a key generated and store on your YubiKey.

Evaluating additional authentication factors

Before generating a new ssh key to store on your YubiKey you must consider which additional required authentication factors you want to use. Below you can see a table with the available factors and their corresponding command:

Git Crash Course for Beginners

Preface

A good understanding of Git is an incredibly valuable tool for anyone working amongst a group on a single project. At first, learning how to use Git will appear quite complicated and difficult to grasp, but it is actually quite simple and easy to understand.

Git is a version control system that allows multiple developers to contribute to a project simultaneously. It is a command-line application with a set of commands to manipulate commits and branches (explained below). This tutorial will help you get started, and in no time you will be a Git Ninja!
