DUNE and Mudlet both support Transport Layer Security (TLS).

Connections to Dune using TLS are encrypted so that your password and other data are secure at all times. By contrast, when you connect to Dune on the telnet port (6789), there is no encryption and your password and all other data are transmitted insecurely over the internet.
