How to copy SSH keys to another machine?

Public key authentication is generally safer than password-based and is way more convenient.

SSH offers a command to set it up, ssh-copy-id (part of the openssh client package) will copy your public key to the remote machine. Use it like this:

ssh-copy-id -i ~/.ssh/my_key.pub remote-machine

You’ll be prompted your password, and your public key will be appended to the remote machine’s ~/.ssh/authorized_keys file.

Note: Remember to use ssh-keygen to first generate a pair of keys if you don't have any.
