I use the CredentialPicker class to present a familiar user interface . This, as expected, stores the credentials in the Windows Credential Manager. EDIT: code example here
However, the recommended way to store your username / password is the PasswordVault API - Best Practices for Storing Confidential Data in Windows 8 - which looks like a different system in general?
What is the right way for both: introduce a familiar user interface and 2. add, access and delete the metropolis style username / passwords?
I am using C #, but the answers in C ++ and JS will be fine.
