What is the purpose of using SSO in security contexts?

The purpose of using Single Sign-On (SSO) in security contexts is primarily to simplify user authentication. SSO allows users to log in once and gain access to multiple applications or systems without needing to enter their credentials repeatedly. This not only improves user experience by reducing the number of times individuals must sign in but also enhances security management by limiting the credentials users need to keep track of.

By centralizing the authentication process, SSO makes it easier for organizations to manage user accounts and enforce security policies. It helps in reducing the potential for password fatigue, which can lead to weaker security practices, such as using the same password across multiple sites.

When implemented correctly, SSO can also facilitate enhanced security measures, such as multi-factor authentication, to further protect user identities while maintaining a seamless user experience. This integration of security and usability is a key benefit of SSO in cloud environments and enterprise applications.
