SSH Keys

SSH keys are required to securely access your GPU instances. You must add at least one SSH key before launching an instance.

Adding an SSH Key​

  1. Go to Dashboard > SSH Keys
  2. Click Add SSH Key
  3. Enter a name for your key (e.g., "my-laptop")
  4. Paste your public key (starting with ssh-rsa, ssh-ed25519, etc.)
  5. Click Save

Generating an SSH Key​

If you don't have an SSH key yet, generate one on your local machine:

macOS / Linux​

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

When prompted:

  • Press Enter to accept the default file location
  • Optionally set a passphrase

Then copy your public key:

cat ~/.ssh/id_ed25519.pub

Windows​

Using PowerShell:

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

Or use PuTTYgen to generate a key pair.

Managing SSH Keys​

Viewing Your Keys​

Go to Dashboard > SSH Keys to see all your registered keys with their names and public key fingerprints.

Deleting a Key​

  1. Go to Dashboard > SSH Keys
  2. Click the delete button next to the key you want to remove
warning

Deleting an SSH key does not revoke access to currently running instances that were launched with that key. It only prevents the key from being used for future instance launches.

Using SSH Keys with Instances​

When launching an instance, you'll select which SSH key(s) to attach. After the instance is running, connect via:

ssh ubuntu@<instance-ip>

Replace <instance-ip> with the IP address shown in your dashboard.
