Jitsi Meet prosody is the engine behind authentication and messaging in Jitsi’s open-source video calls. Whether you’re a developer getting to know Jitsi’s setup, a business owner curious about secure user management, or an agency offering white-label video solutions, understanding Prosody is key. This server handles real-time messaging and controls how users log in and interact safely. In this article, we’ll cover what Prosody does, its API, how the UI ties into it, branding options, example tweaks, and useful resources—all with straightforward insights for your projects.
Jitsi Meet’s real-time chat and presence run on XMPP, an open XML-based protocol for instant messaging and user status. Prosody acts as the lightweight XMPP server—it’s written in Lua and handles authentication, presence, multi-user chats, and signals between clients.
Prosody connects with Jitsi Meet components through configured interfaces to keep authentication secure, control access, and route messages:
Authentication: Prosody supports several auth methods. The simplest stores credentials internally. For bigger setups, it can connect to external LDAP or use JWTs (jitsi token auth). Token authentication is handy for cloud or container-based environments since it’s stateless.
Message Routing and Presence: Prosody manages call signals like invites, presence updates, and chat messages. Low latency here is crucial for smooth calls.
API Interactions: Prosody doesn’t have a REST API by default but offers Lua module hooks. You can write your own modules to customize authentication flows, listen to events, or connect third-party services. This lets developers build custom auth or integrate external messaging.
A startup linked Prosody to their LDAP directory so employees could sign in with single sign-on. They set up Prosody’s LDAP modules and didn’t have to tweak the frontend much. It cut support requests and boosted security fast.
Prosody mostly runs behind the scenes, but it shapes the UI elements related to auth and messaging in Jitsi Meet.
Login Screens: When secure auth is on, the login forms change depending on the method—asking for usernames, passwords, or tokens. These forms talk to Prosody to check credentials live.
Password Prompts and Errors: If login fails because of bad credentials or config issues, users see clear error messages based on what the server sends back. This depends on good Prosody integration.
In-Call Messaging: Chat, presence icons, and participant status updates come through XMPP stanzas Prosody delivers. Things like “Participant joined,” “Muted,” or chat bubbles all rely on data from Prosody.
In an education-focused white-label project, devs added custom branding to the login screen and an extra “Terms of Use” checkbox before signing in. They did this by tweaking React components that connect with Prosody’s auth flow, keeping the experience smooth and real-time.
Branding helps make Jitsi Meet feel like it belongs to your company or client. Combined with Prosody auth, you can customize login and messaging screens in several ways:
Custom Logos and Colors: Add your organization’s logo to the login and meeting UIs for consistent branding.
Custom Login Messages: Display instructions or disclaimers on auth pages by changing Prosody config and frontend code. Businesses often add security or privacy notes here.
Domain-based Branding: Advanced setups detect users’ domains and change branding dynamically—great for agencies offering white-label tools to multiple clients on the same Prosody server.
Localization and Language: Translate auth messages and UI labels by editing language files and making sure Prosody’s error texts show properly.
A healthcare provider tied custom branding to HIPAA compliance. They added login disclaimers via the UI and linked these with Prosody auth logs to keep solid audit trails. It helped build trust with patients and staff.
Changing Jitsi Meet prosody authentication and messaging mixes server and frontend work. Here are some practical ideas:
Use JWTs for stateless login. Configure Prosody’s token module (mod_auth_token) to check JWTs when users connect.
Steps:
config.lua to enable mod_auth_token with a shared secret.This makes scaling easy since Prosody doesn’t store sessions.
Change React components to add extra stuff on login screens, like checkboxes or inputs that talk to Prosody’s auth backend.
Example: An age consent checkbox before login.
Add Lua modules in Prosody to log every auth attempt for compliance and security. Send logs to external management tools if you want.
Set Prosody up with multiple virtual hosts, each for a different client domain. Each can have its own auth system, welcome messages, and access rules.
Write Lua scripts in Prosody to automate in-call messages—like welcoming new users or sending helpful tips.
Many agencies using Jitsi Meet inside corporate networks build custom auth bridges with Prosody plugins and add welcome message templates. It smooths out onboarding and helps users settle in.
