Learn more about Windows.Security.Credentials.PasswordVault and its safety.

I am developing an app at UWP.I learned that Windows.Security.Credentials.PasswordVault exists as a way to store credentials such as username and password.However, there was little information on whether it was a relatively new feature, and I couldn't find a document stating what kind of personality it was.

• Q1: The linked reference mentioned above is

  Apps and services don't have access to credentials associated with other apps or services.

  It says , but can I think that Apps here refers to each application that I am developing (in other words, what is the basis for the identity of Apps)?

• Q2: Where and under what conditions are the credentials stored by this API?If it is not accessible (unless you do much) using this API, it is certainly safe.
