Server SSH Keys ​

SSH Keys for servers allow you to grant secure access to specific system users on the server. This page helps you manage SSH keys that have been added to individual system users on your server.

TIP

Server SSH Keys are different from Global SSH Keys. Global keys are automatically added to all new servers when you create them, while server SSH keys are specific to individual servers and system users.

Access the management page ​

  1. Navigate to your server detail page
  2. Click on the SSH Keys tab in the server navigation menu

The page displays a table with all SSH keys currently added to the server, showing:

  • Name: memorable name for the SSH key
  • System User: the Linux user that this key grants access to
  • Created By: the team member who added this key (shown with avatar)
  • Date Created: when the key was added to the server

Add SSH Key to the server ​

Step 1: Open the create dialog ​

Click the "Add SSH Key" button in the upper right corner of the page.

A dialog appears with the title "Add SSH Key".

Step 2: Fill in the information ​

Option 1: Generate key automatically

  1. Click the "Generate SSH Key" button in the upper right corner of the dialog
  2. The system automatically generates a new ED25519 SSH key pair and fills in the form
  3. A yellow warning banner displays: "This private key is only issued once, please download the backup"
  4. You must download the following files immediately:
    • OpenSSH Key: private key for Linux, macOS, and Windows OpenSSH (file format: {name}.key)
    • PuTTY Key: private key for PuTTY on Windows (file format: {name}.ppk)
    • Public Key: the public key (file format: {name}.pub)

Option 2: Enter existing key

Fill in the following fields manually:

  • Name: a memorable name for this SSH key (e.g., "John's Laptop", "Deployment Key")
  • System User: select the Linux system user that this key will grant access to (e.g., flashpanel, root, or any custom user you've created)
  • Public Key: paste the SSH public key content (format: ssh-rsa AAAA... or ssh-ed25519 AAAA...)

Step 3: Complete ​

Click the "Add SSH Key" button to add the key to the server.

The new key will appear in the list. The system automatically installs the key into the selected system user's authorized keys file.

Delete SSH Key ​

To remove an SSH key from the server:

  1. Locate the key in the list
  2. Click the trash icon button in the Actions column at the end of the row
  3. A confirmation dialog appears asking you to confirm the deletion
  4. Click "Delete" to confirm

The key will be removed from the server's authorized keys file and the user will no longer be able to connect using that key.

Important

  • Private keys are only displayed once when automatically generated. You must download and save them immediately
  • Deleting an SSH key is immediate and cannot be undone. Make sure you have backup access before removing keys
  • Keys are tied to specific system users. If you delete a system user, their SSH keys are also removed

Use cases ​

Development team access: Add SSH keys for each developer on your team, granting them access to specific system users based on their role.

Deployment automation: Create dedicated SSH keys for CI/CD pipelines to deploy applications without using passwords.

Multiple device access: Add separate SSH keys for your laptop, desktop, and other devices you use to connect to the server.

Client access: Grant temporary SSH access to clients or contractors by adding their public keys, and easily revoke access by deleting the keys when needed.
