What functionality does Okta's Single Sign-On (SSO) provide?

Okta's Single Sign-On (SSO) provides the functionality that enables users to access multiple applications with one set of credentials. This is a powerful feature that enhances user experience and security by eliminating the need for users to remember multiple usernames and passwords for different applications. With SSO, when a user authenticates once, they gain access to all connected applications without having to log in again for each one.

This streamlining of access not only simplifies the login process but also reduces the risk of password fatigue, where users might resort to insecure practices, such as using simple passwords or writing them down. SSO supports user productivity and enhances security management by centralizing access control, making it easier to implement security policies across multiple applications while reducing the potential attack vectors associated with handling multiple login credentials.

While improving password strength, allowing multiple users to access a single application, and enabling applications to share user data are important aspects of user management and security, they do not specifically define the core functionality of Single Sign-On, which focuses primarily on providing streamlined access to multiple applications through one set of credentials.
