How to Implement B2B SSO for SaaS User Authentication

3 minutes read

In this digital era, enhancing user experience with secure, user-friendly solutions is paramount for SaaS companies. One such crucial component is the efficient implementation of Business to Business (B2B) Single Sign-On (SSO). Although SSO offers a myriad of benefits, the process of implemenation can be intricate. To simplify this, we explore three distinct approaches that can assist you in navigating this landscape.

Method 1: Leverage the Power of Native Authentication SDKs

In this method, the strategy is to utilize the native Software Development Kit (SDK) that corresponds to the programming language of your SaaS solution. For instance, a Java-based SaaS solution could utilize Spring Security SAML, a library rich in features for adding SAML-based SSO authentication to applications developed with Java and Spring Boot.

In the same vein, Python-based SaaS platforms might choose to use Python3-SAML, an implementation of the SAML standard for Python, ideal for Django-based applications.

This approach, while affording complete customization, necessitates robust coding skills and a comprehensive understanding of SAML-based identity solutions. The requirement to execute multi-tenant SSO further compounds the complexity — varying identity providers like Microsoft Entra ID (Azure AD), Google, Ping or Okta demand extensive engineering resources and time.


  • Full customization options
  • No third-party subscription fees


  • Requires extensive technical expertise
  • Significant engineering resources and potentially lengthy timeframe required due to varied identity provider structures

Method 2: Deploy Third-party Authentication Services

Third-party services like Auth0 or Amazon Cognito are designed to mitigate some of the multi-tenant SSO complexity using identity federation. Nonetheless, the use of these services requires a firm grasp of their suite of SDKs and APIs to properly integrate them into your application architecture.

Understanding SSO protocols like SAML or OIDC are a prerequisite. Additionally, session management within your applications remains within your purview, adding another layer of complexity. Adequate proficiency in using these third-party SDKs and APIs, coupled with the correct application, is crucial, which potentially extends the implementation timeline.


  • Eases the complexity of managing the multi-tenant SSO process


  • Requires a significant understanding of the third-party SDKs, APIs, SSO protocols like SAML or OIDC, and session management
  • Extensive engineering resources and time are needed

Method 3: Embrace No-code Authentication with Datawiza

As an alternative to the traditional code-centric approach, Datawiza offers a no-code, configuration-based solution. This approach eliminates the need for programming and protocol-specific understanding, which significantly reduces the learning curve and simplifies the execution process. For a more detailed explanation of this approach, visit our solution page here.


  • Minimal coding requirements
  • Simplified and expedited implementation process


  • Potential third-party service costs

To sum up, here’s a table that compares the three methodologies:

Method Expertise Required Engineering Resources Needed Time Taken
Native Implementation (e.g., Spring Security SAML for Java) High Extensive Several Months
Third-party Service (e.g., Auth0, Amazon Cognito) Moderate Significant Few Months
No-code Solution (Datawiza) Low Minimal Few Minutes

While each approach has its own set of advantages and challenges, the choice depends primarily on each company’s specific needs, resources, and technical capabilities. Yet for businesses seeking an efficient and straightforward path, Datawiza’s no-code solution emerges as a compelling option in the quest to implement B2B SSO for SaaS user authentication.
