Which of the following configurations is NOT possible for password policies in IdentityNow?

In IdentityNow, password policies are designed to ensure security while providing flexibility for different use cases. The configuration that is not possible is requiring different policies for the same source. This is because each source can only have one password policy associated with it at any given time.

In contrast, using the same policy across multiple sources is entirely feasible, allowing organizations to maintain consistency in password rules for similar types of systems. Additionally, creating a custom policy for unique sources is supported, enabling tailored security measures based on specific requirements of different sources. Adjusting complexity requirements is also possible, granting organizations the ability to enforce different levels of complexity in passwords as per their security standards.

Thus, the ability to require different policies for the same source does not align with the structure of IdentityNow's password policy system, making it the correct identification of what is not possible within the platform’s configurations.
