How To Use SFTP to Securely Transfer Files?

Hello everyone,
I’m looking for some guidance on using SFTP (Secure File Transfer Protocol) to securely transfer files between my local machine and a remote server. I understand that SFTP is more secure than FTP because it encrypts the data during transfer, but I’m not entirely sure how to set it up and use it effectively.
Could someone please give me the basics of setting up SFTP?
Any tips, commands, or resources would be greatly appreciated!
Thanks in advance.
