Details

=======

This module allows clients to register an account using an invite ('preauth')

token generated by mod_invites. It implements the protocol described at

[docs.modernxmpp.org/client/invites](https://docs.modernxmpp.org/client/invites)

and [XEP-0401 version 0.3.0](https://xmpp.org/extensions/attic/xep-0401-0.3.0.html).

**Note to developers:** the XEP-0401 protocol is expected to change in the future,

though Prosody will attempt to maintain backwards compatibility with the 0.3.0 protocol

for as long as necessary.

This module is also responsible for implementing the optional server-side part

of [XEP-0379: Pre-Authenticated Roster Subscriptions](https://xmpp.org/extensions/xep-0379.html).

**Note to admins:** Loading this module will disable registration for users

without an invite token by default. Control this behaviour

invite token.

an invite token.
