SFTP (SSH File Transfer Protocol) is a secure method for transferring files between computers over a network. Unlike regular FTP, which sends data in plain text, SFTP encrypts both commands and data, protecting your information from interception. This makes it essential for managing website files, backups, and sensitive data on hosting servers.

SFTP operates on port 22 by default, using the SSH (Secure Shell) protocol to establish a secure connection. To connect, you need:

• SFTP client software (like FileZilla, WinSCP, or Cyberduck)
• Your server hostname or IP address
• Username and password (or SSH key)
• The correct port number

Key advantages of using SFTP include:

• Enhanced security through encryption
• Reliable file transfers with error checking
• Ability to resume interrupted transfers
• Support for file permissions and operations

Most web hosting providers include SFTP access in their plans, allowing you to securely upload website files, manage directories, and perform maintenance without risking data exposure.

For beginners, using SFTP is similar to regular FTP but with the crucial benefit of security. Always ensure your hosting provider supports SFTP and consider using it instead of standard FTP for all your file transfer needs.
