## Prepare 2nd slot
Now it's time to prepare the second slot of your YubiKey for the challenge response authentication. Touch will be also enabled.
Now it's time to prepare the second slot of your YubiKey for the [challenge response authentication](https://wiki.archlinux.org/index.php/yubikey#Challenge-Response "Setup YubiKey Challenge-Response").
Touch will be also enabled. You can also install the package `yubikey-personalization-gui`. It allows for customization of the secret key,
creation of secret key backup and writing the same secret key to multiple YubiKeys which allows for using them interchangeably for creating
same *ykfde* passphrases.
> Securely save the 20 byte length secret key from the output, so you can use it to initialize another YubiKey as backup.
