Explanation
Single Sign-On (SSO) is the authentication method that allows a user to authenticate once and gain access to multiple applications without re-entering credentials.
Common mistakes.
- B. Permission propagation refers to the automatic inheritance of access rights from parent objects to child objects in a directory or file system, not to authentication across applications.
- C. Inheritance in security contexts describes how permissions flow from parent to child resources; it is an access control concept unrelated to how users authenticate across multiple applications.
- D. MFA (Multifactor Authentication) requires a user to present multiple verification factors during login and does not address reducing repeated logins across multiple systems.
