SSH keys provide secure, password-less access to your GPU instances. Add your public key to Runcrate, and it will be injected into any new instances you deploy.

​
Generating a Key Pair

If you do not already have an SSH key pair, generate one:
This creates two files:
  • Private key — ~/.ssh/id_ed25519 (keep this secret)
  • Public key — ~/.ssh/id_ed25519.pub (upload this to Runcrate)

​
Copying Your Public Key

​

Give the key a recognizable name (e.g., macbook-pro, work-desktop).
4

​
Managing SSH Keys

The SSH Keys tab shows all keys in the current workspace:

​
Deleting a Key

Click Delete to remove an SSH key from the workspace.
Deleting an SSH key from Runcrate does not remove it from currently running instances. It only prevents the key from being added to future deployments.

​
Supported Key Types

​
Multiple Keys

You can add multiple SSH keys per workspace. All keys will be injected into new instances, allowing multiple team members or machines to connect.
