+summary: 'Disable access control for all OMEMO related PEP nodes'
+---
+
+Introduction
+============
+
+Traditionally OMEMO encrypted messages could only be exchanged after gaining mutual presence subscription due to the OMEMO key material being stored in PEP.
+
+XEP-0060 defines a method of changing the access model of a PEP node from `presence` to `open`. However Prosody does not yet support access models on PEP nodes.
+
+This module disables access control for all OMEMO PEP nodes (=all nodes in the namespace of `eu.siacs.conversations.axolotl.*`), giving everyone access to the OMEMO key material and allowing them to start OMEMO sessions with users on this server.
+
+Disco feature
+=============
+
+This modules annouces a disco feature on the account to allow external tools such as the [Compliance Tester](https://conversations.im/compliance/) to check if this module has been installed.
+
+
+Compatibility
+=============
