What are the three ways to manage authentication in NetSuite?

The correct answer highlights the methods available for managing authentication in NetSuite by including Inbound Single Sign-On (SSO), Outbound SSO, and Token-Based Authentication.

Inbound SSO allows users to access NetSuite using their existing credentials from an external identity provider. This method simplifies the user experience by facilitating seamless navigation between the identity provider and NetSuite, making it particularly beneficial for organizations that have a centralized identity management system.

Outbound SSO refers to the ability of NetSuite to integrate with other applications and platforms using single sign-on, offering a versatile way to manage authentication across multiple systems. This ensures users have a consistent login experience without needing to remember multiple sets of credentials.

Token-Based Authentication provides a secure way to authorize API requests. By using tokens instead of traditional usernames and passwords, this method enhances security by limiting the exposure of credentials, which is especially advantageous for integrations and automated processes.

These elements together provide a comprehensive approach to authentication in NetSuite, supporting various user scenarios and security requirements. Other options may mix correct and incorrect methods or terminology which would not accurately represent the current capabilities NetSuite offers for managing authentication.
