SSO is an authentication process that allows users to sign on to their applications and services with a single set of credentials.
SSO establishes trust between the identity provider (IdP) and the service provider (SP). The IdP handles the identity information that authenticates the user requesting SSO, and the SP handles the service or application that the user wants to access.
Identity standards such as SAML, OAuth2, and OpenID Connect enable the secure sharing of identity data among multiple SPs and IdPs. Without standards, each connection would require customized development. The following graphic illustrates how SSO streamlines the sign-on process by giving employees secure, one-click access to resources or services from any device.
During SSO, an IdP uses an accepted identity standard of communication, such as SAML, to pass an encrypted assertion between the user and the SP. If the user is successfully authenticated through SSO, they have secure, one-click access to a variety of services without the need for repetitive credential entry, multiple passwords, or separate accounts.
To enable SSO, the IdP must implement a centralized authentication server that all apps can use to confirm a user’s identity. This server can validate user identities and identity or access tokens with data that confirm the user’s identity, privileges, and granted authorizations.
The following diagram illustrates the standard steps of SP-initiated federated SSO.

Every day, our digital world presents us with more systems and applications to use in our lives. Creating and remembering complex passwords for every app is a challenge and potentially a security risk. By implementing SSO, you can give your customers, employees, and partners the ability to access different applications and services easily, quickly, and securely.
