Test

    [TestCase("-Username ABC -Password XYZ -Address MNO", "-Username ABC -Password *** -Address MNO")]
    public void Test(string toTest, string expected ) 
    {
        Assert.AreEqual(expected, DestroyPassword(toTest));
    }

Code

    public static string DestroyPassword(string str )
    {
          var r = new Regex("-Password .*? ");//? in .net means not greedy
          return r.Replace(str, "-Password *** ");
    }
