The main advantage of single sign-on (SSO) technology is that it simplifies the user experience by allowing individuals to access multiple applications and services with just one set of credentials. This minimizes the need for users to remember numerous passwords, reducing the likelihood of password fatigue and enhancing security by lowering the chance of weak password practices. SSO also streamlines authentication processes and helps organizations manage user access effectively, often integrating with identity and access management (IAM) systems. By improving efficiency, SSO can boost productivity and ensure a more secure and user-friendly approach to application access for both enterprises and users.
