I've been using LastPass for the past two years (If i remember correctly) and i had three occasions when after recovering my Master Password and resetting it, their systems didn't sync my data properly and locked me out of my account (As the new Master Password wouldn't work despite being recently changed). I contacted them but i was greeted with a "We can't change the password or do anything at this point". They don't even take care of their systems and they don't take responsibility for their lack of experience on handling systems.
