I've had folk ripping on about files in the cloud being held hostage as well. Files and your data are our responsibility. We only lose what we don't backup.
LastPass is the last password program I would recommend. Their dysfunctional program is holding my passwords hostage. After a hard disk crash, their system would not follow their written directions no matter how many times they were applied. Email has not receiverd any response other than the same failing directions. Email asking for my files to be sent to me has never been responded to in any way, just ignored.
Your passwords are at risk by LastPass' lack of customer support and their irresponsability. The program worked until service was needed. It has been more than a year since the ordeal began and about 100 passwords are unretriveable.
LastPass also purchased X-marks, then shut it down. Many years of email addresses were on my account. When X-marks closed, all my records disappeared. None were on my computer at all, but were on a cloud of pollution. My estimete is that about 200 business and individual's email addresses just disappeared.
LastPass has no solution to erscape their indifference and lack of responsibility to customers. Collect your information and serve yourself before something happens. Roboform or Dashlane are better choices, especially because they actually have customer support.
