Security by design

ProtonXMPP fills the gap between usability and rock-solid security on XMPP services. It is based on open source software built by a community composed of end-users, developers and service providers around the world.

Some of our XMPP features are:

ProtonXMPP is supported by a strong security foundation:

SSL encryption

Secure Sockets Layer (SSL) encrypts the connections between parts of the Jabber network, the same method that is used to encrypt website traffic (HTTPS). We always require encryption and use only the strongest available encryption methods.

Secure password storing

Unlike many other Jabber/XMPP servers, we no do not store passwords in plain text but encrypt them using the Blowfish algorithm.

ProtonXMPP features “In Band Registration”, which means that you can register an account directly from your client. ProtonXMPP recommends using Pidgin as your IM client. Download pidgin here.

If your client does not support “In Band Registration”, we offer a web-based registration option here.


We believe in free communication

ProtonXMPP is built and maintained by a group of developers from around the world. We believe that communication between individuals should be free and without borders. We're aimed at disrupting proprietary, non-open standards-based instant messengers. See our Privacy Policy here.
