What is Single Sign-on (SSO)
Single sign-on, or SSO, allows a user to access multiple applications using a single set of credentials. This capability can be applied to both employees and customers to streamline their login experiences. Typically, employees sign on to multiple business applications to do their jobs, such as messaging and email accounts, HR functions, intranet sites, financial records, etc. With SSO, they can access all of the resources they need with one set of login credentials, eliminating the need to remember or enter a unique password for each account.
Similarly, customers often access multiple services or applications through one business account or portal. Banking is a good example. As shown in the diagram below, SSO makes it possible for bank customers to sign on with a single set of credentials and be able to perform a variety of actions like checking their account balance and transferring money. Even if these services are actually separate applications managed by the bank behind the scenes, SSO provides your customers with a seamless experience.
