Very disapointing. It seemed to have magically changed my master password so I'm locked out of my account. I had stored so many important passwords using it and I used their password generator multiple times. To make matters even worse, their Customer Care cannot help you reset your password. (Apparently they store all of your passwords locally on your device but how true can that be?) My advice, don't waste your time on this rubbish password manager.

Update: It seems my password changed back to my former LastPass password and I've lost some data. The only problem with LastPass is if you ever lose your master password you're screwed.
Another Update: Scratch 'some' of my data; EVERY single saved password is gone. Don't bother using LastPass
