What is a key benefit of using AWS SSO (Single Sign-On)?

A key benefit of using AWS Single Sign-On (SSO) is that it enables users to access multiple assigned applications with a single set of credentials, allowing for one-click access. This feature streamlines the authentication process, eliminating the need for users to remember multiple usernames and passwords for different applications. As a result, it enhances user experience by saving time and reducing frustration associated with managing multiple logins.

In addition to improving usability, this capability also strengthens security by minimizing the risk of password fatigue, which can lead to weaker security practices like reused passwords. Moreover, AWS SSO integrates seamlessly with existing identity providers, allowing organizations to centrally manage user access across many applications easily. This simplified access not only helps in productivity but also provides a harmonious way to maintain security policies across various services.

The other options, while they relate to important aspects of cloud services, do not align with the primary function and benefits of AWS SSO. For instance, simplifying billing for multiple AWS services pertains to financial management rather than user authentication, while centralizing monitoring of AWS resources relates to operational oversight, and enhancing data encryption focuses on security rather than access management.
