This automatically adds your key to the Pi: $ ssh-copy-id pi production servers, I tend to turn off password authentication and only allow authorized SSH keys. To do this, I use the ssh-copy-id command to copy it to the Pi. If I’m working on a Pi at home or work, I tend to leave SSH settings at their default, as I’m not concerned with security on an internal trusted network, and I usually copy my SSH key to the Pi to avoid having to authenticate with a password every time. You can share the public key (id_rsa.pub) with others or place it on other servers. Keep the private key (id_rsa) on the PC and never share it. This will create a key-pair (a public and private key) in ~/.ssh/. To create an SSH key, run the command: $ ssh-keygen SSH keys are a way to authenticate SSH connections without using a password, either to speed up your access or as a security measure, if you turn password access off and ensure only authorized keys are permitted. Over time I’ve come up with a few time-saving tips and tools that you might find useful, too.
