What technology could Mark use to manage multiple passwords for different applications?

Single Sign-On (SSO) is a technology that allows users to access multiple applications with a single set of login credentials. This is particularly beneficial for managing multiple passwords, as it eliminates the need for users to remember and input different passwords for each application they use. With SSO, once a user logs in, they gain access to all associated applications without the need to re-enter their credentials.

SSO enhances user convenience and productivity, reducing the time spent on logging into various services, while also contributing to security by minimizing the risk of password fatigue. When users have fewer passwords to remember, they are less likely to use weak passwords or resort to writing them down, which can pose security risks.

In contrast, options such as discretionary access control (DAC), role-based access control, and user-based access focus on how permissions are assigned and managed within systems rather than specifically addressing password management. While these are important concepts in access management, they do not provide the same streamlined password handling capabilities that SSO offers.
