Top 10 SSO Providers You Must Consider in 2024

Single Sign-On (SSO) has become a SaaS essential. The popular authentication method allows companies to use trusted third-parties to authenticate users easily. SSO providers handle all authentication activities and save the business valuable development time since no proprietary authentication system is required. Interested in implementing a SSO solution? We have shortlisted the top options you must consider in 2024.

How Do Single Sign-On Solutions Work?

Firstly, let’s look at things from the perspective of the end-user. It’s pretty straightforward. Once the user has logged into the application successfully, it catches on all applications using exactly the same single sign-on (SSO) tool. Furthermore, SSO tools can be used with multiple protocols – Security Assertion Markup Language (SAML), OpenID Connect, and more.

As shown in the illustration above, the initial action is checking for SSO cookies. When it’s a first time login, there is no SSO cookie. The user then utilizes one of the predefined login methods, following which an SSO cookie (with an expiry date) is created for future use. The user can then proceed to using the application with minimal fuss.

Main benefits of using SSO platforms include:

  • Added ease of use for end-users, which enhances customer satisfaction
  • Less stress on developers to create new authentication solutions
  • Improved security and compliance capabilities
  • A seamless experience that is easy to integrate
  • Better and easier to manage, especially while scaling up fast
