What is single sign-on (SSO)

Single Sign-On (SSO) is a method of authentication that allows users to access multiple applications and services with a single set of login credentials. Instead of having to remember and enter multiple usernames and passwords, users can log in to multiple systems using a single set of credentials. This can save time and reduce the risk of password-related security breaches.

SSO is typically implemented using a centralized authentication server, which acts as a gatekeeper for all the applications and services that a user needs to access. When a user attempts to log in to one of these systems, the authentication server is notified and checks the user's credentials. If the credentials are valid, the user is granted access.

There are several different types of SSO, including:

  • Federated SSO: This type of SSO uses a third-party service to authenticate users. The third-party service, called an identity provider, manages the user's credentials and verifies them when a user attempts to log in to an application or service.
  • SAML SSO: Security Assertion Markup Language (SAML) is an open standard for exchanging authentication and authorization data between systems. SAML SSO uses SAML to securely exchange authentication data between systems, allowing users to log in to multiple systems with a single set of credentials.
  • OAuth SSO: OAuth is an open standard for authorization. OAuth SSO uses OAuth to allow users to grant access to their resources without sharing their credentials.
  • OpenID Connect: OpenID Connect is an open standard for authentication. It allows users to authenticate with an identity provider, and then use that authentication to access multiple services.

SSO has many benefits, including:

  • Improved security: SSO reduces the risk of password-related security breaches by eliminating the need for users to remember multiple usernames and passwords.
  • Increased productivity: SSO saves users time by eliminating the need to log in to multiple systems with different credentials.
  • Better user experience: SSO improves the user experience by making it easier for users to access the resources they need.

However, SSO also has some challenges, such as:

  • Complexity: SSO can be complex to implement and manage. And hence Pensil provides complete developer support to integrate SSO with Pensil community. You can read more about the
  • Single point of failure: If the SSO system goes down, users will not be able to access any of the applications or services that rely on it.
  • Dependence on third-party providers: Federated SSO relies on third-party identity providers, which can introduce additional risk.

Overall, SSO is a powerful authentication method that can improve security and increase productivity. However, it is important to carefully consider the costs and risks associated with SSO and to choose the right type of SSO for your organization's needs. A good SSO solution should be easy to use, highly secure, and scalable to meet the needs of your organization as it grows. It should also be flexible enough to accommodate different types of authentication methods and protocols so that you can easily integrate it with other systems and applications.
