Keycloak OpenID Connect Integration for the Vodia PBX
Published on:
September 12, 2025
Vodia’s PBX now integrates with Keycloak OpenID Connect, providing secure single sign-on for users so they can access all connected applications without repeated authentication. Logging out from one application automatically logs the user out of all connected systems, simplifying user management and improving security. Keycloak, a Cloud Native Computing Foundation project, supports standard protocols including OpenID Connect, OAuth 2.0, and SAML, offering enterprise-grade identity and access management. To ensure proper integration, Keycloak user emails must match the corresponding PBX extension emails. Complete guidance is available in the Vodia Keycloak integration guide.
Vodia’s PBX now supports Keycloak OpenID Connect, enabling secure single sign-on for your users. Once a user logs in through Keycloak, they can access all connected applications without repeated authentication. Logging out from one application also logs the user out from all connected systems, simplifying user management and improving security.
What Is Keycloak?
Keycloak is a Cloud Native Computing Foundation (CNCF) incubation project. CNCF is the open source, vendor-neutral hub of cloud native computing, hosting projects such as Kubernetes and Prometheus that make cloud native universal and sustainable. A number of global organizations have recently shared their Keycloak case studies, including the Austrian Business Service Portal, Hitachi, and OpenTalk.
How Keycloak Works
Vodia users can now authenticate with Keycloak, rather than with individual applications, so these apps don’t require authenticating users, login forms, and storing users. Once a user logs in to Keycloak, it isn’t necessary to log in again to use another application.
This also applies to logging out, as Keycloak enables single-sign out (SSO): once a user logs out of an application, this user is automatically logged out of all applications using Keycloak. Keycloak is based on standard protocols and provides support for OpenID Connect, OAuth 2.0, and SAML.
The Integration of the Vodia Phone System with Keycloak
The integration of the Vodia phone system with Keycloak provides enterprise-grade identity and access management.
This allows for secure Single Sign-On (SSO), but Keycloak user emails must match the corresponding extension email addresses on the PBX.
The Vodia phone system is the best choice for enterprises and SMBs looking to build feature-rich, robust, scalable, and secure business communication ecosystems that integrate with the world’s best business communications software - our integration with Keycloak OpenID Connect is just the latest in a series of integrations we’ve completed with some of the world’s best business communications software, including ActiveCampaign, Freshdesk, HighLevel, Microsoft Dynamics 365, monday.com, and Odoo Cloud, among others. We want our customers to have everything they need to build external and internal communications stacks that drive growth and profitability.
Vodia PBX strengthens security with passkeys, giving users and administrators a secure, passwordless login method that eliminates many vulnerabilities tied to traditional credentials. Passkeys use public key cryptography, storing the private key on the user’s device and the public key on the server, making them resistant to phishing and credential theft. By reducing reliance on passwords, Vodia minimizes the attack surface in cloud environments and makes authentication simpler and more secure, while ensuring a smoother, faster login experience for all users.
Many organizations rely on Microsoft as the foundation of their daily operations, but their communication systems often exist in parallel rather than in harmony. Vodia closes that gap by bringing telephony into the same environment where teams already work, turning separate systems into one connected structure. This approach removes friction between platforms, simplifies management, and gives IT teams better control and visibility over daily communication. It also creates a more seamless experience for employees, reduces operational overhead, and builds a stronger, more flexible foundation that supports growth, collaboration, and long-term scalability.
Vodia will be attending CVxExpo 2025 in Glendale, Arizona, from November 3–5. Sales Engineer Eric Altman will be on site to meet with current and prospective partners, demonstrating how Vodia’s PBX solutions can strengthen technology roadmaps for 2026. This year, Vodia highlights new integrations with ActiveCampaign, Freshdesk, HighLevel, Microsoft 365, Microsoft Presence, monday.com, and Odoo Cloud, along with enhanced call center capabilities such as agent activity dashboards, call recordings, and transcription features. Partners and attendees can schedule meetings with Eric to learn more about scalable, feature-rich, and cost-effective telecommunications solutions built for enterprises and SMBs.
