Key Derived Function (KDF) enables YubiKey to store the hash of PIN, preventing the PIN from being passed as plain text. Note that this requires a relatively new version of GnuPG to work, and may not be compatible with other GPG clients (notably mobile clients). These incompatible clients will be unable to use the YubiKey GPG functions as the PIN will always be rejected. If you are not sure you will only be using your YubiKey on supported platforms, it may be better to skip this step.

Run the following commands:
> git config --global core.sshcommand 'plink -agent'
> git config --global gpg.program 'C:\Program Files (x86)\GnuPG\bin\gpg.exe'
```console
git config --global core.sshcommand "plink -agent"
You can then change the repository url to `git@github.com:USERNAME/repository` and any authenticated commands will be authorized by YubiKey.
git config --global gpg.program 'C:\Program Files (x86)\GnuPG\bin\gpg.exe'
```
You can then change the repository URL to `git@github.com:USERNAME/repository` and any authenticated commands will be authorized by YubiKey.
**Note** If you encounter the error `gpg: signing failed: No secret key` - run `gpg --card-status` with YubiKey plugged in and try the git command again.
