I develop a simple SharePoint Hosted App and deploy but when i open this app, there is popup for id and password. which id password i need to enter because they dont accept administrator id password
Is this happening on the local server? Is your app domain separate from your host domain? If so, you will need to disable the loopback check to avoid this problem (since you wouldn't be able to add BackConnectionHostNames values to the registry for every dynamically generated app URL).
