Each provides an additional layer of security on any Windows, OS X or Linux machine by requiring you to present something you have - in this case a program or key that generates a one-time password at login time - as well as something you know: your user ID and master password that unlocks your password database. In fact, it offers three different options for two-factor authentication.
Of the four password management programs I reviewed this week, LastPass was the only one to support two-factor authentication (I'll post a link to the full review on Monday, when it launches). This is particularly important if you use a product designed to synchronize your password data with other devices by way of a master database hosted in the cloud, as LastPass does.
If you're going to use a password manager from a mobile computer that travels outside of your office, two-factor authentication can provide an extra layer of security.
