As more companies build SaaS platforms, the need to serve multiple customer groups—or tenants—from a single system becomes critical. In the identity world, this means implementing multi-tenancy within your identity provider.
In this post, we’ll walk through:
We've written extensively about how to model multi-tenancy with organizations and how Phase Two's Organizations extension differs from the native implementation being undertaken by the Keycloak team.
All of Phase Two's hosted environments come standard with all of our popular extensions to make it easy to hit the ground running and cover 95% of all IAM use-cases.
As more companies adopt Keycloak for enterprise identity and access management, security is no longer just a back-end concern. One of the most frequent questions we hear at Phase Two is:
"Should I put a Web Application Firewall (WAF) in front of Keycloak?"
The short answer? It depends—but it's a smart question to ask.
In this post, we'll break down what Keycloak provides out of the box, explore common attack vectors (especially around authentication endpoints), and help you evaluate whether you need to add an external firewall or WAF to your deployment.
Passwords are on their way out. From phishing to password reuse, they've become one of the weakest links in modern authentication. The solution? Passkeys—a phishing-resistant, user-friendly, and increasingly supported replacement for traditional passwords.
In this post, we’ll break down what passkeys are, how they work, which platforms support them, how they relate to WebAuthn, and how you can integrate them into your Keycloak authentication flows. Finally, we’ll explore some of the real-world considerations and challenges.
SAML has a bit of a reputation. For many developers, it lives in that shadowy corner of the B2B internet where XML still rules and stack traces seem to go on forever. If you've ever had the misfortune of debugging a malformed <Assertion>, you know the pain. But here's the thing: it doesn't have to be a nightmare.
At Phase Two, we provide managed hosting and enterprise support for Keycloak, a leading open-source Identity and Access Management platform. And while OIDC has become the default for most modern applications, SAML is still alive and well—especially in enterprise environments.
This post is a gentle (and opinionated) introduction to what SAML is, how it works, and why it still matters particularly if you're implementing SAML SSO in Keycloak.
When implementing SAML for the establishment of an Identity Provider, two primary options are available:
The SP initiated flow is widely recognized by users due to its straightforward configuration, which is merely the exchange of some metadata. In contrast, the IdP-initiated flow is less intuitive and involves an additional step that may not be readily apparent to many users. The purpose of this blog is to elucidate the steps necessary to successfully execute the IdP-initiated flow. We will setup a full example
A fundamental understanding of SAML 2.0 and Keycloak is required to effectively follow the provided instructions.
When it comes to identity and access management, Keycloak has established itself as the go-to open-source solution for authentication, authorization, and user management. However, successfully integrating and maintaining Keycloak requires more than just hosting—it requires expertise. That’s where the difference between Phase Two and other hosting providers becomes clear.
In this post, we’ll explore why Phase Two should be in strong consideration for your Managed Keycloak provider, especially when compared to providers like CloudIAM, Elest.io, and Servana, who focus solely on hosting the standard build of Keycloak.
In this series we are proposing Keycloak as a superior alternative to commercial identity offerings.
At the heart of every startup's decision-making process lies the bottom line. We’re in an economy where cost-cutting measures are being taken across organizations, and many companies are starting to ask why their identity stack is such an outsized drag on their margins. Keycloak presents a compelling case with its open-source nature. Unlike proprietary IAM solutions that come with hefty price tags and recurring subscription fees, Keycloak offers a cost-effective alternative without compromising on features or security.
By leveraging Keycloak, startups can significantly reduce their operational expenses, channeling those resources into core business activities such as product development and market expansion. Moreover, the open-source community surrounding Keycloak ensures continuous improvement and innovation, all without the burden of additional licensing costs.
A multi-tenant application is a software architecture where a single instance of an application serves multiple, distinct customer groups or “tenants.” Each tenant, often representing an organization or user group, shares the same underlying infrastructure and codebase but operates within its own securely isolated environment. This allows each tenant to have individualized data, configurations, and sometimes even unique customizations, while benefiting from a shared platform that reduces overall resource demands and maintenance. Multi-tenancy is commonly used in SaaS (Software as a Service) applications, enabling businesses to scale efficiently, lower costs, and streamline updates while ensuring that each tenant’s data and settings remain private and distinct from others within the same application. This approach is particularly valuable in enterprise applications, where companies may need to provide access to different organizations, departments, or customer groups within a single solution.

One size rarely fits all, especially in the world of enterprise software. Startups require flexibility to adapt and tailor IAM solutions to their unique business requirements. Keycloak shines in this aspect, offering extensive customization capabilities that empower startups to mold the platform according to their specific needs.
From branding and user interface customization to advanced authentication flows and authorization policies, Keycloak provides a comprehensive toolkit for startups to craft seamless and secure user experiences. Whether integrating with existing systems or building entirely new functionalities, Keycloak's flexibility ensures a perfect fit for any enterprise SaaS startup. Here’s how Keycloak’s flexibility stands apart from commercial, closed-source solutions, and why this is a key differentiator:
