Hi guys, I am using facebook's open graph API in java. I have a login button on my page. When call the login API of facebook then facebook's login screen appears. Till this point I have no any problem. Now when I enter email Id and password and click on login button then facebook's login page appears again prompting to enter password again. A security warning also aapears on the top of the page. Can anyone let me know why the login page appears again.
