New users can register their details and create an account using Register option at the time of Login. Existing users can login with their registered username (email id) and password.
If you are having trouble logging in, click on the ‘forgot password’ link in the Login page. An email with a new password will be sent to your registered email ID which can then be used for logging in. You can also change your Password through 'change password' option available in ‘My Accounts’.
Alternately you can also sign in using your social media accounts of Facebook and Google plus. Please note that QDF does not store your social media password. ‘Forgot password’ feature is only valid for users registered with QDF website and not for login using social media.
