Single Sign-On (SSO) is the appropriate authentication method because it enables users to authenticate once and gain access to multiple applications without re-entering credentials. This streamlines the login process and enhances user experience while maintaining security. Multifactor Authentication (MFA) increases security by requiring multiple authentication factors but does not allow access to multiple systems without additional logins. Federated Identity Management allows sharing of identity information across different organizations or domains, which may not be applicable here. Biometric Authentication uses unique physical traits for identity verification but doesn't provide access to multiple systems with a single authentication.
