| SSH keys are a convenient way to perform passwordless authentication with the cluster's ssh interface. These are generated using ``ssh-keygen`` on your workstation (linux, Mac, or WSL). You can generate either with or without a local passphrase, which provides more security, although it slows some single-command functions like ``scp``. SSH keys have no lifetime and are distinct from time-limited [[X509_keys]],though either can be used for passwordless authentication. | SSH keys are a convenient way to perform passwordless authentication with the cluster's ssh interface.

| After you generate the key with ``ssh-keygen`` on your workstation, copy the new public key ``~/.ssh/id_ecdsa.pub`` to your home directory on the cluster (not the corresponding ``~/.ssh`` directory on the cluster, where it might overwrite the cluster's keys). You will still need a password for this file copy, or you can use the file manager on the OOD or Globus portals, as the key is not active yet. | After you generate the key with ``ssh-keygen`` on your workstation, copy the new public key ``~/.ssh/id_ecdsa.pub`` to your home directory on the cluster (not the corresponding ``~/.ssh`` directory on the cluster, where it might overwrite the cluster's keys).
