| In Linux, you can use the **Secure Copy Protocol** (**[[cs101:scp|SCP]]**) from the command line ([[cs101:cli|CLI]]) (the scp command) to securely copy files and directories between remote hosts without explicitly logging into the remote systems. The scp command uses [[cs101:ssh|SSH]] to transfer data, so it does requires a password or passphrase for authentication.
