Setting up your SSH keys First, verify that you have the latest version of SSH installed. As your regular user, open a PowerShell terminal and type `ssh -V`

Once that has been verified, execute the following command in Powershell. `ssh-keygen.exe -t ed25519-sk -O resident -O verify-required -O application=ssh:key9.dev` The -t flag specifies the type of key to be generated by OpenSSH. We intend to use ED25519 with the "Security Key" option, indicated by the -sk at the end. Additionally, the -O verify-required option mandates the input of a PIN before the SSH key can be utilized. After execution, you should see something link the below. Select the "Security Key" option.

You may encounter the following screen, which you should click on "OK".

The software is letting you know ssh-sk-helper.exe is about to be executed

At this point, you'll be ask to enter your Yubikey's PIN.

After you click "okay," it may seem like the setup is finished, but it's not. You will be taken back to a Powershell. In Powershell, you will be asked to enter a "file to save your key" and a "passphrase." If you only have one key, it's best to just press "enter" for the file location. This is also the default location OpenSSH will look for the key. When prompted for a "Passphrase", simply hit "enter". Our key will be signed with our Yubikey and there is no need for a "Passphrase". In short, you can hit "enter" through all the prompts. You should see something like the below.
