2. Establishing an Account:

To begin, you must establish an XMPP account. For the purposes of this guide, we shall create one on a website.

– Open the TOR Browser and navigate to the following link: https://jabber.hot-chilli.net/

– Subsequently, click on “Account” and “Create Account”:

Upon viewing the account creation page, select your desired username, Jabber domain, and ensure your chosen password consists of a minimum of 35 characters: https://passwordsgenerator.net/. It is imperative to update this password on a bi-weekly or monthly basis:

– Complete the Captcha challenge and click on “Create Account”. If all information is accurately provided, you shall be presented with a confirmation prompt indicating the successful establishment of your account.

– Now, open Pidgin. Should the Accounts window be visible, select ‘Add’. If it is not, proceed by navigating to Accounts > Manage Accounts, or alternatively, press the key combination Ctrl+A.

– Subsequently, from the Protocol dropdown menu, select ‘XMPP’.

– Provide your username and corresponding password.

– For the ‘Domain’ field, insert the details of the XMPP server.

Prior to clicking on “Add”, navigate to the ‘Advanced’ tab. In this section, you have the option to input a .onion address for the connect server.

– Lastly, to ensure all traffic to and from your account is routed via Tor, proceed to the ‘Proxy’ tab.

For the ‘Proxy type’, select ‘Tor/Privacy (SOCKS5)’.

Input ‘127.0.0.1’ for the ‘Host’ field.

Enter ‘9050’ for the ‘Port’ field if you are using the Tor service, and ‘9150’ if you are using the Tor Browser:

Click add.

– To activate the OTR plugin, navigate to Tools > Plugins and place a tick in the box adjacent to Off-the-Record Messaging.
