Is TFTP safe to use?

TFTP is an unauthenticated, plain-text file transfer protocol. It is commonly used to transfer files and images. No password is required, just a straight “Get this file ” or “Put this file ”. It uses UDP to transfer data. It is designed to be very simple, and light-weight.

The TFTP server has no security. How do you know that the file was uploaded from your device? What’s stopping a bad actor from retrieving all your files? Or uploading malicious files?

Our recommendation--Don't use it!
