Check if you already have an available SSH key

ls $HOME/.ssh

If the files id_ed25519 and id_ed25519.pub are in the ~/.ssh folder, you don’t need to follow this guide, you already have your SSH key.

Create a new SSH key pair

ssh-keygen -t ed25519

Follow the instructions to generate a new SSH key pair. You will be asked to encrypt you private key with a password. This step is optional but for further security you may want to set one.

By default both private and public keys will be located in your $HOME/.ssh directory.
