I accidently scanned the wrong finger on LastPass, and it logged me on! Then I asked my mother to scan her finger, and her finger worked too! What's wrong here? I haven't bought LastPass. (I'm just trying the fingerprint scanner. It's a trial on 15 days or so..) Could this be because my trial has ran out? (If so I don't think LastPass is good when it comes to security!)

UPDATE: According to my Device Manager, I have one of the Validity Sensors fingerprint scanners. I use a Dell Vostro 3350 with an i3, so maybe you know exactly which one it has. I use it to log into Windows, and here it works perfectly!

You should probably get a different password manager. That company has already been hacked twice and now anyone is scanning their finger and accessing your passwords?

Yes, but if they get hacked, can the hackers get anything out of the passwords, as they don't have the master pass thus the encryption key? – Friend of Kim Feb 24 '12 at 20:08
Nope they can't. Lastpass is using a very strong encryption method (PBKDF2-SHA-256) and a brute-force attack is near impossible. If you are paranoiac about brute-force attacks, you can increase iterations to make brute-force attacks even more unlikely… . I consider myself a paranoiac. That's why I use 10 000 iterations! – Eric Gagnon Jun 16 '12 at 16:57
