I will say that I am reviewing this from a free user perspective. If anyone wants to see a review of the pro, and how yubiKey works with LastPass. Although Hak5 has done a bunch of episodes on using yubiKey's, and LastPass.
~ compliant w/ all of the major operating systems:Linux/mac/windows/BSD(sadly no haiku)
~ has a two factor authentication w/ cards, to perform two factor auth. with the free version.
~ has a security check for checking the strength of your passwords.
(there were three fast screens that flew by encrypting passwords, sending passwords, calculating password strength...)
~ Imports from almost any format, but doesn't export into many formats.
~ Secure notes for keeping "secret" Lists.
(you can also copy/paste anything in one of thise lists you want.)
~ one click filling of form-data
(although I use AutoKey 2 automate strokes portably from inside a encrypted volume)
~Generate secure Passwords...
|The LastPass Password generator, to give you an unlimited amount of random passwords.|
Although I think the main advantage from using any kind of password dataBase, is going to be the ease of use it is for (possibly-incompentent non-tech. users)to enter propperly strong passwords, and to easily change them if they find out their NT was attacked.
