what makes xmpp a trustworthy way to communicate with others?

Question

• An Overview of XMPP
• Luke Smith recommends XMPP

As Luke Smith said in his video, XMPP has been designed as an open communication protocol, which is similar to the email at an extent, I am wondering why people consider it as a safe communication method. So far as I know, the XMPP protocol itself doesn't provide any encryption to ensure the visibility of messages to only the sender and receiver. So, how does XMPP protocol protection work?

Answer 1

It isn't.

XMPP Chat is a federated protocol just like email.

• It may or may not use TLS client to server, but generally does these days.
• The federated servers hold and relay clear text chat just like email.
• End-to-End encryption is dependent upon client side body encryption just like email.
