In an informatics context, what does SSO stand for?

Single Security Option
System Security Organization
Single Sign-On
Secure Sign-On

The correct answer is: Single Sign-On

In the context of informatics, SSO stands for Single Sign-On. This term refers to an authentication process that enables users to access multiple applications with one set of login credentials. The primary benefit of SSO is enhanced user convenience, as it eliminates the need to remember various usernames and passwords for different services, thereby reducing the risk of password fatigue and potential security weaknesses associated with managing multiple credentials. SSO works by creating a centralized authentication model where, upon logging in to one application, the user is automatically recognized and granted access to other linked applications without needing to log in again. This process not only simplifies the user experience but also enhances security by minimizing the number of times users have to enter sensitive information. Additionally, SSO can streamline administrative processes, as it allows for easier user management and monitoring. Organizations often implement SSO to improve workflow efficiency and bolster security across multiple systems while ensuring that user access can be controlled and audited effectively.
