Single Sign-On (SSO) is a process that allows users to access multiple applications with a single set of credentials (username and password), without having to log in to each application separately. The goal of AuthO SSO is to increase convenience and security for users by reducing the number of passwords they need to remember, and by providing a central point of control for administrators.
This article describes the basics of SSO and how to implement SSO with Auth0, a commercial authentication and authorization service.
This is part of a series of articles about Auth0.
In this article:
Auth0 is an authentication and authorization platform for SaaS applications and services. The platform provides a wide range of features and tools to help developers secure their applications, including SSO, multi-factor authentication (MFA), and social login. With Auth0, developers can add authentication to their applications, without having to worry about the underlying security details.
In addition to providing authentication services, Auth0 also offers a robust set of APIs and integrations with popular identity providers such as Google, Facebook, and Microsoft. This allows developers to leverage existing identities and workflows, and to add new features to their applications with ease.
SSO allows a user to access multiple SaaS applications with one single set of login credentials. When a user signs in to one application, they are automatically signed in to all other applications that are connected to the same SSO system.
This is achieved by using a central authentication service, which verifies the user’s identity and then generates a token that can be used to access other applications. The token is typically passed between the applications through a secure connection, and the user is not required to enter their login credentials again.
Auth0 uses Universal Login to define the login flow, a key feature of the authorization server. Every time a user attempts to prove their identity, the application redirects to Universal Login and Auth0 works to guarantee the user’s identity.
Universal Login does not require any integration work to handle authentication. You can start using a simple username and password, and add additional features like MFA and social login. This process works dynamically and can be adjusted in real time without any application-level changes.
When setting up SSO with Auth0, the Auth0 Authorization Server serves as the Central Service. Here is an example of how the SSO flow works when a user first logs in:
Implementing Auth0 SSO typically involves the following steps:
It’s important to keep in mind that implementing SSO with Auth0 requires a solid understanding of application security, as well as the ability to code and integrate the Auth0 SDK into your application. If you’re not familiar with these concepts, you may need to seek the help of a security expert or a software development consultant.
When using Auth0 for SSO, you should consider the pros and cons. The following points are based on publicly available reviews published on Software Advice.

Now that we have understood how Auth0 SSO works, it’s equally important to see how much work (and time) can be saved with Frontegg’s self-served user management platform. Once you’re in, all you need to do is enable SSO, configure it (something that just takes a few minutes), and define the customer identity provider. It just takes a few clicks and doesn’t take your focus away from what really matters – innovation.
