On JetHost shared hosting you can log in over SSH with your cPanel password, but a key is safer. Learning how to **generate an SSH key** is worth it, because key-based authentication is nearly impossible to brute-force or guess. This guide shows you how to generate an SSH key in cPanel.

## Why use an SSH key?

A key comes in two parts: a public key kept on the server and a private key kept on your computer. Because no password travels over the network, key-based login resists brute-force attacks and lets you connect without typing a password each time. You can reuse the same key across your devices, and revoke it instantly if a device is lost.

## Generate an SSH key in cPanel

When you generate an SSH key, a public key is stored on the server while the matching private key is saved on your computer. Follow these steps:

1. In cPanel, open **SSH Access** and click **Manage SSH Keys**.
2. Click **Generate a New Key**.
3. Enter a key name and a strong passphrase.
4. Choose the key type. **RSA** is the recommended, widely supported option.
5. Click **Generate Key** to create the key pair.
6. Click **Manage** next to the new key and **authorize** it. Without authorization you cannot use it to connect.

## Download and convert the private key

Next, download your private key so you can use it in an SSH client. Some clients, such as PuTTY, only read keys in `.ppk` format. To convert it, click **View/Download** next to the private key, enter your passphrase, and click **Convert**. Download the `.ppk` version for Windows, or keep the standard key for Mac and Linux. Store the private key safely and never share it.
