What aspect of connected apps allows for single sign-on (SSO) functionality?

The aspect of connected apps that enables single sign-on (SSO) functionality is the use of OAuth and SAML. Both technologies are integral to modern authentication processes.

OAuth is a widely used authorization framework that allows third-party services to exchange user data without sharing passwords. When implementing SSO, OAuth can facilitate access tokens that grant permissions to access various services while maintaining user sessions across applications.

SAML (Security Assertion Markup Language) is another key technology that supports SSO. It is specifically designed for exchanging authentication and authorization data between parties, primarily enabling web-based SSO by allowing users to authenticate once and gain access to multiple applications without needing to log in again for each application.

Together, OAuth and SAML provide a secure and efficient means to enable users to access multiple applications seamlessly while ensuring that their credentials remain protected. This dual framework allows connected apps to streamline user authentication and enhance the user experience significantly, making it more convenient for users to access various services without repeated logins.
