Share Windows Credentials across multiple Windows Store Apps (Win 10)

Details:

I have two sample Uwp apps. Both has use fallowing method:

private string GetPasswordCredential()
{
    PasswordVault passwordVault = new PasswordVault();
    PasswordCredential passwordCredential = null;

    try
    {
        var passwordCredentials = new List<PasswordCredential>(passwordVault.RetrieveAll());
        if (passwordCredentials.Any(c => c.Resource.Equals("testResource") && c.UserName.Equals("testUserName")))
        {
            passwordCredential = passwordVault.Retrieve(resource: "testResource", userName: "testUserName");
        }
    }
    catch (Exception exception)
    {
        var message = exception.Message;
    }

    if (passwordCredential == null)
    {
        // create credential deteils
        passwordCredential = new PasswordCredential(resource: "testResource", userName: "testUserName", password: "testPassword");

        // add credential details to password vault
        passwordVault.Add(passwordCredential);
    }

    return passwordCredential.Password;
}

The problem is that, the method creates unique Credentials for every app: enter image description here

My aim is to create one Credential detail if not exists, and use it by second App as well once second App gets run. The above method logic does a check but also create brand new Credential for each App. Only difference I can see 'Saved By' section. How can I force second App to grab/use already existed Credential?

How can I force second App to grab/use already existed Credential?

You can't. The offical documentation is pretty clear on the fact that "the contents of the locker [represented by the PasswordVault class] are specific to the app or service. Apps and services don't have access to credentials associated with other apps or services.".

So App2 cannot access a credential created by App1 and vice versa. This is by design.
