When you start a conversation make sure that the OMEMO box is ticked. You can also click on the keys button and trust various fingerprints. Both sides will need to do that before an encrypted chat can start.

The <a href="https://profanity.im">Profanity</a> shell based user interface and is perhaps the simplest way to use XMPP from a laptop. It's also a good way to ensure that your OTR keys are the same even when logging in from different laptops or devices, and it also means that if those devices later become compomised then there are no locally stored OTR keys to be found.

Tor Messenger is a messaging client which supports XMPP, and its onion routing enables you to protect the metadata of chat interactions to some extent by making it difficult for an adversary to know which server is talking to which. You can download Tor Messenger from <a href="https://torproject.org">torproject.org</a> and the setup is pretty simple.
