SSH Keys

Overview​

SSH Keys are a secure way to connect to your Instances without using passwords.
By adding your public key to the Cerebro Cloud, you can log into any Instance where that key is authorized.

You can:

  • Add multiple SSH keys under Workspace Settings → Credentials.
  • Mark one key as the default (used for all Instances unless another is specified).
  • Assign different SSH keys to specific Instances if you prefer.

Adding an SSH key​

  1. Navigate to Workspace Settings → Credentials.
  2. Click Add a new SSH key.
  3. Fill in the form:
    • Name – Required, up to 200 characters. Suggested automatically based on your key’s comment (e.g., [email protected]).
    • SSH Key – Required. Must be in a supported format.
  4. Paste your key in the field (Placeholder: “Paste your SSH key here…”).
  5. Click Add.

Before saving, the system validates your SSH key format and type. If invalid, you’ll see an error message.
