Which are valid Service Now User Authentication Methods? (Choose three.)

XML feed is typically used for data import/export or integration between systems, not as a direct user authentication method for logging into the platform.

The local database is a fundamental authentication method where user credentials are stored and verified directly within the ServiceNow instance, useful for internal or non-integrated users.

LDAP (Lightweight Directory Access Protocol) integration allows ServiceNow to authenticate users against an external corporate LDAP directory, synchronizing user data and credentials with an existing identity provider.

SSO (Single Sign-On) enables users to authenticate once and gain secure access to multiple systems, including ServiceNow, without re-entering credentials, often utilizing protocols like SAML 2.0 or OAuth 2.0.

FTP (File Transfer Protocol) authentication is used for file transfers between systems and is not a supported method for authenticating users into the ServiceNow platform itself.
