`xmpp-cloud-auth` (aka `xcauth`) started as a simple program to free [JSXC – The Open Chat](https://www.jsxc.org) for [Nextcloud](https://www.nextcloud.com) from having to remember and reuse passwords: The password entered for Nextcloud login would need to be captured and stored in the browser in such a way that malware could also access it. The project is written primarily in Python, distributed under the MIT License license, first published in 2017. Key topics include: ejabberd, external-auth, nextcloud, postfix, prosody.

For installation and configuration instructions, see doc/Installation.md. :warning: Especially if you plan to use it on Prosody, as their mod_auth_external.lua does not work around a bug in lpty.
