The number one source of complaints and worries with mobile apps is users complaining they have to enter their Microsoft or PSN username and password into an app before it can access the private Destiny API. They are quite right to be worried as those credentials give access to credit card based services, private email and highly valuable game libraries with related data. I doubt any of us want to touch these details, but we have no choice. There is no genuine Oauth or other way to authenticate our apps to get the Bungie account details and access the full API. Can you give us a heads up on if you have any plans to address this?
