All of us are aware of the YubiKey hardware device that offers encryption and safe authentication of stored data, as well as the creation and management of public and private keys, preventing unauthorized personnel from accessing the key or the certificate details stored in the device.

Also, the YubiKey device can be used in multiple processes like Key generation and CSR attestation, which are primary tasks required for [obtaining code signing certificate](https://signmycode.com/code-signing-certificates) using the YubiKey Manager tool.

After you receive your OV or EV code signing certificate successfully, the next step is installing your code signing certificate on the YubiKey device using the same YubiKey Manager tool. 

Hence, let's glance through an easy-to-follow tutorial enabling you to install your code signing certificate on the YubiKey without any hassles.

## Step 1
