I used the free version for about 2 years. A few months ago I upgrade to the paid version for mobile support. It works greats. I think maybe one site I use has some weird form that lastpass doesn't recognize so I have to manually copy and paste to login.you using the free version? saw a pay for use option for something like $12/year
How exactly are you doing this? Everything I can dig up with Google is for DropBox or Google Drive.
If it happened once, it can happen again.
Was my master password exposed?
No, LastPass never has access to your master password. We use encryption and hashing algorithms of the highest standard to protect user data. We hash both the username and master password on the user’s computer with 5,000 rounds of PBKDF2-SHA256, a password strengthening algorithm. That creates a key, on which we perform another round of hashing, to generate the master password authentication hash. That is sent to the LastPass server so that we can perform an authentication check as the user is logging in. We then take that value, and use a salt (a random string per user) and do another 100,000 rounds of hashing, and compare that to what is in our database. In layman’s terms: Cracking our algorithms is extremely difficult, even for the strongest of computers.
