Secure Server Authentication

Secure Shell (SSH) provides a encrypted way to access your server’s command line. While traditional password authentication is available, using SSH Keys is significantly more secure and convenient. It uses a pair of cryptographic keys (Public and Private) to verify your identity without sending a password over the network.

Uploading a Public Key

To use SSH key authentication, you must upload your Public Key (id_rsa.pub or similar) to the Web Panel.
1

Access SSH Manager

Log in to the Web Panel and go to the Security tab, then select SSH keys.
2

Add Key

Click the Add Key button.
3

Paste Your Key

  • Name: Give the key a descriptive name (e.g., My Laptop).
  • Key Content: Paste the entire contents of your public key. This usually starts with ssh-rsa, ssh-ed25519, or ecdsa-sha2-nistp256.
4

Save

Click Add. The system will automatically configure your account to recognize this key.

​
Connecting via SSH

Once your key is uploaded, you can connect using a terminal (macOS/Linux) or a client like PuTTY (Windows). Command Line Example: ssh [email protected] Connection Details:
  • Host: Your domain or the Main IP.
  • Port: Default SSH port 22.
  • User: Your hosting account username.

​
Benefits of SSH Keys

Passwords can be guessed or “cracked” by automated bots. SSH keys are virtually impossible to brute-force because of their extreme cryptographic complexity.
Once set up, you can log in instantly without typing your password every time. This is especially useful for developers who frequently use terminal commands or automated deployment scripts.

​
Protect Your Private Key

Never share your Private Key with anyone. Only the Public Key should be uploaded to the server. If your private key is compromised, delete the corresponding public key from the Web Panel immediately.
