Single Sign-On Solutions: Key Features and Top Vendors

Single sign-on (SSO) solutions provide an authentication solution that allows users to enter credentials once and access multiple connected systems. SSO facilitates central access control for IT admins, who can manage authentication via a local SSO server or a third-party provider. Because they provide improved management capabilities, SSO solutions are especially useful for rapidly expanding organizations.

Several types of solutions have single sign-on capabilities today: 

  • SSO is a common feature in identity management (IdM) platforms
  • SSO is often bundled with multi-factor authentication and other authentication technologies
  • Some providers offer single sign-on as a standalone solution, either on-premises or hosted in the cloud

Read on to understand how SSO works and discover the key features of modern Single Sign-On solutions. To top it off, we’ll also introduce you to the top 8 SSO solutions you need to shortlist today before making your decision.

How Do SSO Logins Work?

Whenever a user logs in to a SSO service, it generates an authentication token to remember the user for future sessions. The authentication token is a piece of digital information stored on a user’s browser or the server. 

This token grants the user access, via the SSO service, to all applications the user needs to access.  When a user wants to sign in, the Single Sign-On service passes the authentication token to the app and allows access without asking them for credentials again. If users are not logged in, the application redirects them to the Single Sign-On service for authentication.

SSO services do not store the user’s ID, so they usually are not aware of the identity of specific users. Typically, Single Sign-On services integrate with an identity management service and match a user’s credentials to user data stored there. Single Sign-On is an intermediary that can verify that a user’s login credentials match their identity without managing the user database itself.

7 Key Features Of Modern SSO Solutions

Here are some key features you should look for in a SSO solution:

  1. Customization—an SSO solution should let you customize the end-user experience. You should be able to adapt the login screen to your brand look and feel and have an easy way to turn additional features, like social login or MFA, on and off. 
  2. Integrations—an SSO solution should come pre-integrated with common identity providers and social login providers. The solution should also give you an easy way to integrate in-house systems. 
  3. Mobile experience—modern Internet users are mobile-first, and SSO solutions should follow suit. Ensure the SSO solution provides a smooth, convenient experience for mobile users on any device or screen size. 
  4. Security—a critical feature for SSO. Ensure that SSO encrypts user data, supports MFA to prevent social engineering, and integrates securely with active directory (AD) or LDAP to exchange user data.
  5. Scale—traditional on-premise SSO solutions were difficult to scale up to support more users or additional applications. Modern cloud-based solutions are elastically scalable, letting you support any scale, from hundreds of users to millions.
  6. Support for organizations—some SSO solutions only support end-users directly interacting with the system. If you are a B2B or SaaS company, you need to support an entire organization using their product. Each organization will have its own set of users. Check if the SSO solution provides the ability to manage organizations conveniently.

Uptime—SSO solutions are mission-critical, and if they are down, the applications they support are inaccessible. Opt for cloud-based solutions, where the service provider is responsible for reliability and uptime. Check that the SSO provider provides an acceptable SLA.
