"Single Sign-On (SSO) is a powerful authentication mechanism that enhances both security and user experience by allowing users to log in once and gain access to multiple applications without needing to re-enter credentials. It reduces password fatigue, minimizes security risks associated with weak or reused passwords, and simplifies IT management. However, implementing SSO requires careful consideration of security measures, such as multi-factor authentication (MFA) and strict access controls, to prevent unauthorized access in case of credential compromise. Organizations must also ensure seamless integration with their existing identity providers to maximize the benefits of SSO while maintaining a secure environment."
