Confused by the difference between FTP vs SFTP? The simplest way to connect to your website’s server to transfer or manage files is to use an FTP client.
So, what’s the difference between FTP vs SFTP? And is it better to use one over the other?
In this article, we will look for the difference between FTP and SFTP. This will let us to determine which one is ideal for transferring data on the WordPress site.
The key difference between FTP and SFTP is that SFTP transfers data in an encrypted manner over a secure connection, whereas FTP does not. SFTP enables file encryption while transferring files between a web server and a client. Data transfers between an FTP client and a web server are in plain text, making them insecure.
FTP is short for File Transfer Protocol. Using the client/server approach, FTP allows you to transmit data directly between your FTP client and your web server. To transport data, FTP uses two separate channels: a command channel and a data channel. Both of these channels are unencrypted by default, which means bad actors could possibly eavesdrop on the data you’re sending.
SFTP is short for SSH File Transfer Protocol, but it is also known as Secure File Transfer Protocol. SFTP provides the same basic functions as FTP, however it uses tunneling and SSH to execute file transfers, as opposed to FTP’s client-server and direct transfer technique.
The critical difference is security. But other differences are mentioned in the table below.+
