To achieve user authentication against your on-premises identity, which configuration is needed?

1. Identity federation

2. Tokenization

3. Single sign-on

4. Multifactor authentication

The correct answer is: Identity federation

Identity federation is the correct configuration needed to achieve user authentication against your on-premises identity. This approach allows different identity management systems to communicate and recognize each other. It enables users to access multiple applications across different domains while utilizing a single set of credentials. By establishing a trust relationship between the on-premises identity provider and the cloud or external service, identity federation allows seamless authentication and improves user experience. In contrast, tokenization primarily refers to the process of replacing sensitive information with non-sensitive substitutes, often for security purposes and does not directly address user authentication. Single sign-on creates a similar user experience by allowing a single set of credentials to access multiple applications, but it still often requires an underlying identity federation structure to link the user’s identity across different domains. Multifactor authentication adds an extra layer of security by requiring more than one form of verification regardless of whether identity federation is in place, but it does not constitute a means of authenticating against an on-premises identity system on its own.
