Build LMS Single Sign-on (SSO) Using a REST API

Build SSO in an LMS

Single sign-on (SSO) is a mechanism that allows users to log in once and gain access to multiple systems or applications without having to log in again. In other words, SSO enables users to authenticate themselves only once and then use their credentials to access multiple services or applications.

With SSO, users can avoid the hassle of remembering multiple login credentials for different systems or applications. Instead, they can log in to a central authentication server once, and the server will authenticate the user and provide them with a token or a session identifier. The token or identifier can then be used to access other systems or applications that are configured to trust the central authentication server.

SSO is widely used in enterprise environments where users need to access multiple applications that are hosted on different servers. SSO can also be used to provide a seamless user experience on consumer-facing websites and mobile applications, where users may need to authenticate themselves multiple times.

There are various protocols and technologies that can be used to implement SSO, such as OAuth, OpenID Connect, and SAML. These protocols define how authentication and authorization are performed across multiple systems or applications, ensuring that the process is secure and reliable.

The Benefits of SSO with an LMS

Single sign-on (SSO) can offer several benefits when used with a learning management system (LMS), which is a software application used to deliver and manage educational content.

Here are some of the key benefits of using SSO with an LMS:


SSO provides a seamless login experience for users by allowing them to access the LMS without having to remember additional login credentials. This can help reduce frustration and increase productivity.

Time Savings

With SSO, users can save time by logging in once and accessing multiple applications or systems, including the LMS. This can be particularly beneficial for busy professionals who need to access the LMS frequently.


SSO can improve security by reducing the need for users to remember multiple login credentials, which can lead to weak or compromised passwords. Additionally, SSO can provide centralized control over user access, making it easier to manage user permissions and revoke access when necessary.

User Experience

SSO can improve the overall user experience by reducing the number of times users need to log in, and by making it easier to access the LMS from different devices or platforms.

Cost Savings

SSO can help reduce costs by reducing the amount of time and effort needed to manage user accounts and passwords. This can be particularly beneficial for large organizations that have many users accessing the LMS.

To summarize, using SSO with an LMS can provide a number of benefits for both users and organizations. By reducing the time and effort needed to manage user accounts, SSO can improve efficiency, reduce costs, and enhance the overall user experience.

Build SSO Using a REST API

In this scenario, we will assume that we want to build a single sign-on system using a REST API.

Here are the steps to build a single sign-on system using a REST API:

  1. Create a user authentication system: You will need to create a system that can authenticate users. This can be done using various methods such as username and password, social media login, or multi-factor authentication.

  2. Create an SSO service: Next, you will need to create an SSO service that will handle the authentication process and generate tokens that can be used for authentication across multiple applications.

  3. Implement REST API endpoints: Once the SSO service is created, you will need to implement REST API endpoints that can be used by other applications to authenticate users. These endpoints should be secure and require the appropriate authentication credentials.

  4. Integrate SSO into applications: Finally, you will need to integrate the SSO system into each application that requires authentication. This can be done by making API calls to the SSO service to authenticate users and obtain tokens. The applications should then use these tokens to authenticate users without requiring them to log in again.

Here is a sample workflow of how the SSO system would work using REST API:

  1. User logs into the SSO service by providing their username and password.

  2. The SSO service verifies the user's credentials and generates an authentication token.

  3. The user tries to access another application that requires authentication.

  4. The application makes an API call to the SSO service, passing the authentication token as a parameter.

  5. The SSO service verifies the token and returns a response indicating whether the user is authenticated or not.

  6. If the user is authenticated, the application grants access to the user without requiring them to log in again.

  7. If the user is not authenticated, the application redirects the user back to the SSO service to authenticate.

About LMS Portals

At LMS Portals, we provide our clients and partners with a SaaS-based, multi-tenant learning management system that allows you to launch a dedicated training environment (a portal) for each of your unique audiences.

The platform provides a REST API to enable SSO and other application integrations.

The system includes built-in, SCORM-compliant course authoring software that enables most anyone to build engaging courses quickly and easily.

We also offer a complete library of ready-made courses, covering most every aspect of corporate training and employee development.

If you choose to, you can create Learning Paths to deliver courses in a logical progression and add structure to your training program. The system also supports Virtual Instructor-Led Training (VILT) and provides tools for social learning.

Together, these features make the LMS Portals platform the ideal solution for SSO and other application integrations.
