SAP Customer Data Cloud provides a comprehensive suite of features for managing customer identities and authentication. The platform supports modern, user-friendly authentication methods to streamline user experience and enhance security.

Among the available options, Social Login is a core feature, allowing users to authenticate using their existing credentials from various social networks. Phone Number Login offers a passwordless authentication flow where users can register and log in using their mobile number, typically verified via an SMS OTP. To enhance security, SAP Customer Data Cloud supports Multi-Factor Authentication (MFA), which includes Push Authentication, where a login attempt is approved via a push notification sent to the user's registered device.

A. XML token: This is too generic. While SAP Customer Data Cloud supports federation protocols like SAML which use XML-based tokens (assertions), "XML token" is not a distinct authentication method offered by the platform.

C. SSID authentication: This method pertains to authenticating devices to a Wi-Fi network based on its Service Set Identifier (SSID). It is a network-level protocol and is not a feature of SAP Customer Data Cloud for user identity management.
