Further clients
A list of recognised XMPP clients can be found on the
official XMPP website.
There exist clients that are served as a website that can be used from your web browser.
You should be aware of the security implications of such services.
A malicious service provider could change the code of the service and extract your user data
and even end-to-end encrypted messages.
Therefore it is recommended that you only use web clients from servers that you
control or trust. Often you can serve these clients locally.
