It is important, because you don't want hackers to see username and password packets, do you? When you use a service that does not have encryption, through a public network or the internet, hackers can capture the packets and read them cleartext, and they can try hack onto your system with the information from the unencrypted packets.

That is why a lot of software nowadays use packet data encryption, so hackers need to try very hard to attempt to decrypt the packets and hack onto your system, keeping communication from server to client almost secure!
