What is the primary function of Single Sign-On (SSO) in an IT environment?

  1. To require multiple usernames and passwords

  2. To enable users to remember only one ID and password

  3. To enhance application security through complex passwords

  4. To limit application access to certain user roles

The correct answer is: To enable users to remember only one ID and password

The primary function of Single Sign-On (SSO) is to enable users to remember only one ID and password. SSO streamlines the authentication process by allowing users to access multiple applications and services with a single set of credentials. This significantly reduces the number of passwords users need to manage, making it easier for them to remember their login details and reducing the chances of forgotten passwords. By centralizing authentication, SSO not only enhances user convenience but also improves overall security. With fewer passwords to manage, users are less likely to engage in unsafe practices, such as writing down their passwords or using easy-to-guess variations. Additionally, SSO can simplify the management of user access rights and roles, as organizations can control user permissions centrally rather than needing to manage them for each individual application. The other options may describe features or practices related to authentication and access control, but they do not capture the essence of the primary function of SSO, which focuses on providing a simplified user experience through a unified login mechanism.
