Which authentication types can have multiple instances in Relativity?

In Relativity, it's important to understand the instances of authentication types and how they are utilized in the environment. The correct choice highlights that only OpenID and SAML 2.0 allow for multiple instances.

OpenID and SAML 2.0 are both designed to accommodate various external identity providers, enabling organizations to integrate multiple identity sources for user authentication. This flexibility is crucial for environments that need to support different user bases or undergo transitions between identity systems. Each instance can be configured differently to work with different external services, allowing for a customized approach to user authentication.

On the other hand, options such as password and two-factor authentication are generally single-instance elements as they implement a specific mechanism tied to the users' access credentials. Trusted IP ranges also do not allow for multiple instances as they are configured as a set of specific locations from where users can access the system.

This differentiation allows organizations to manage user authentication in a way that aligns with their security policies and operational needs, thus emphasizing the significance of the chosen answer.
