Shame it doesnt work!

After downloading the app, and putting my email in, thats where it fails.
Theres no-where to input a password of your own, and when it comes to logging back in after logging out of the app, you find that apparently you have a password.
I followed many different attempts on all of the URLs to "change password", and kept getting a 404 notice saying the URL can not be found???
Seems very suspicious, so I will not be linking it with my FB account to use it.
