Short for File Transfer Protocol, FTP is the most common way of sending and receiving files between two computers. A good example of how FTP is used today is by web developers, who will connect to their web server using FTP and send updated versions of their web pages to the server.
FTP login and security
Although many FTP servers require logins, many FTP servers also allow anonymous FTP login, which only require a username and e-mail with no password. It is also important to realize that FTP is insecure. When your username and password are sent to the server they're both sent as plaintext and could be intercepted and read. If your server supports SFTP or FTP with TLS encryption, we suggest one of them instead of plain FTP to help keep your information private.
