Add an SSH public key for your hosting account in Plesk (passwordless login)

SSH keys allow you to log in to your hosting account more securely than using a password. Instead of typing the password each time, your computer proves your identity using a key pair.

Before you start

• SSH access must be enabled for your hosting subscription in Plesk.
• You will connect to the service server hostname (from My.GARMTECH), not to your domain name.

Step 1 — Enable SSH access in Plesk

1. Log in to Plesk from My.GARMTECH.
2. Open Websites & Domains → Hosting Settings (or Web Hosting Access).
3. Find SSH access and select a shell (for example /bin/bash or /bin/sh), then Save.

If you do not see SSH options, your plan may not include SSH access.

Step 2 — Generate an SSH key pair

Linux / macOS (Terminal)

ssh-keygen -t ed25519 -C "your-email@example.com"

This creates:

• ~/.ssh/id_ed25519 (private key — keep it secret)
• ~/.ssh/id_ed25519.pub (public key — this is what you add to the server)

Windows

• If you have OpenSSH: open PowerShell and run the same ssh-keygen command.
• Or use PuTTYgen to generate a key pair and export the public key in OpenSSH format.

Step 3 — Add the public key in Plesk

Depending on your Plesk interface, you may have one of these options:

Option A: SSH Keys Manager in Plesk

1. Open Websites & Domains and look for SSH Keys (or SSH Keys Manager).
2. Click Add Key.
3. Paste the content of your .pub file and save.

Option B: Add authorized_keys via File Manager

1. Open Files (File Manager).
2. In your home directory, create a folder .ssh (if it does not exist).
3. Create a file authorized_keys inside .ssh.
4. Paste your public key as a single line and save.

Step 4 — Connect via SSH

Use your hosting system user (often the same as your main FTP user) and your service hostname:

ssh USERNAME@SERVER-HOSTNAME

Troubleshooting

• Permission denied (publickey): confirm you used the correct username and the correct server hostname from My.GARMTECH.
• Key format issues: make sure you pasted the public key (.pub), not the private key.
• Still asked for password: the key may not be applied to the correct user, or SSH access is not enabled for the subscription.
