Why Use SFTP for File Transfers
When it comes to FTP vs. SFTP, there are some key differences to keep in mind. First, no one wants their information to fall into the wrong hands. Second, FTP (File Transfer Protocol) uses clear text for all transmissions.
Anyone can read the FTP usernames, passwords, commands, and data by sniffing the network.
On the other hand, SFTP can securely transfer information. This is because it builds on FTP software and uses the SSH protocol to transfer files, and requires the client to be authenticated by the server for enhanced security elements.
In short, SFTP is designed to be an extension of SSH to provide secure file transfer capabilities.

Connect to SFTP Using FileZilla
FileZilla is a free open source FTP software tool allowing users to transfer files from a local computer to a remote computer. It is capable of running on Windows, Linux, and macOS. FileZilla supports FTP, SFTP, and FTPS protocols.
SFTP provides two user-authentication options when connecting to your server:
- Passwords
- SSH key-based authentication
The SSH Keys are more secure than the password. In this article, we’ll cover both ways.
Please keep in mind that if the server you’re connecting to only supports FTP connections, not SSH connections, you won’t be able to use SFTP.
