What is (S)FTP?

(S)FTP, which commonly stands for Secure File Transfer Protocol or SSH File Transfer Protocol, is a secure method for transferring files between computers over a network. It uses SSH (Secure Shell) to encrypt the data, protecting usernames, passwords, and the file content itself from being intercepted. It's commonly used for uploading website files to a web server, securely transferring sensitive data, and automating file transfers.
