​
Step 1: Open the SSH Keys page

In the left sidebar, navigate to Management → SSH. SSH keys enable secure access to your GPU instances.

​
Step 2: Start adding a new SSH key

Click the green Add SSH Key + button (top-right).

​
Step 3: Get your SSH public key from your local machine

You’ll paste your public key (a .pub file) into the SSH Key field. To find your public key:
  1. List SSH keys on your terminal:
ls -al ~/.ssh
  1. Look for a file ending in .pub (for example: id_rsa.pub or id_ed25519.pub).
  2. Print the key to your terminal (example using RSA):
cat ~/.ssh/id_rsa.pub
  1. Copy the entire output (it usually starts with something like ssh-rsa or ssh-ed25519).
Important: Paste the full line exactly as shown (no extra spaces or line breaks). Tip: If you don’t have a .pub file yet, you can generate one with: 
ssh-keygen -t ed25519 -C "your_email"
Press Enter to accept the defaults, then re-run the commands above to copy your new public key.
To upload the key in AION:
  1. Paste your public key into the SSH Key field.
  2. Enter a recognizable Key Name (for example: your laptop name).
  3. Click Add SSH Key.

​
Step 4: Verify the key is added

Once saved, your key appears in the SSH Keys list. You can now select this key during GPU instance creation from the SSH Key dropdown.

​
Optional: Delete an SSH key

  1. In the SSH Keys list, click Delete on the key you want to remove.
  2. In the confirmation dialog, type the exact key name shown.
  3. Click I understand the consequences. DELETE this resource.
