* SSO stands for Single Sign-On, which is a technology that allows users to log in once and access multiple applications without entering their credentials again1.
* SSO simplifies the user experience and enhances security by reducing password fatigue and enforcing password policies1.
* SSO is an example of an identity and access management (IAM) solution that integrates with different authentication methods and protocols2.
* LDAP, EAP, and TACACS+ are not correct answers because they are not authentication methods that allow access to multiple applications after logging on. They are protocols that facilitate authentication, authorization, and accounting (AAA) functions3.
* LDAP stands for Lightweight Directory Access Protocol, which is a protocol that provides access to directory services that store information about users, groups, and devices3.
* EAP stands for Extensible Authentication Protocol, which is a framework that supports various authentication methods, such as passwords, certificates, tokens, and biometrics3.
* TACACS+ stands for Terminal Access Controller Access-Control System Plus, which is a protocol that provides centralized AAA services for network devices and users3.
