Top 7 SSO Providers You Must Consider in 2021


Single Sign-On (SSO) has become a SaaS essential today. The popular authentication method enables companies to rely on a trusted third-party to authenticate all of their users easily. SSO providers or services essentially 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 decided to shortlist the top options you must consider in 2021.

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, SSO tools are reached when the user tries to login. 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 into existing SaaS ecosystems
  • Better and easier to manage, especially while scaling up fast
  • Before we closely inspect the best SSO software you can get today to bolster your SaaS offering, this list primarily includes Service Provider Initiated (SP-initiated) tools. We also have to clarify beforehand that this list is not exhaustive in any way or form. We invite you to add your own recommendations in the comments section below or share your personal experience with the ones we are featuring here.

#1 – Okta

This popular identity management vendor has been providing a solid cloud-based Single Sign-On solution for years now.  Why is Okta so popular? Firstly, it has the ability to integrate all end-user web and mobile applications via their own IdP. The password reset option on offer is fully self-served. However, end-users have to perform a wide range of personalization and setup actions while getting started.
