What is a Single Sign On(SSO)?
Single sign-on (SSO) is an authentication solution that allows users to securely authenticate to multiple applications and websites using a single set of credentials. For example, logging in to your Google account once will allow you to access Google applications such as Google Docs, Gmail, and Google Drive.
Without an SSO solution, the website maintains a database of login credentials – usernames and passwords. Each time the user logs in to the website, it checks the user’s credentials against its database and authenticates the user.
With the SSO solution, the website does not store login credentials in its database. Instead, Single Sign On (SSO) makes use of a shared cluster of authentication servers where users are only required to enter their login credentials once for authentication. With this feature of one login and multiple access, it is crucial to protect login credentials in SSO systems. Hence it is highly recommended to integrate SSO with other strong authentication means such as smart tokens or one-time passwords to achieve multi-factor authentication.
Introduction of Single Sign On (SSO)
Single Sign On(SSO) is a session and user authentication service that allows a user to access various apps using a single set of login credentials, such as a username and password. SSO is used by every organization as well as individuals to manage multiple credentials more efficiently.
