When Facebook threw up that window, LastPass choked and cancelled the password change. But since I saw the dialog that Facebook put up, I answered it and elected to remain logged in to my other devices. When this happened, Facebook said my password was successfully changed, but LastPass hadn't registered the switch.
Actually, it wasn't that hard to fix. LastPass saved its attempt to change my Facebook password as a "Generated password for..." entry meaning I could swap out the old password manually and keep everything up-to-date.
Another hiccup came when I was tried to change the password to one of my Google accounts in Chrome.
I am usually signed in to multiple Google accounts at once. When I tried to change one of my Google accounts, LastPass failed since it couldn't navigate through some of the screens multiple account users have to deal with, such as the page where you have to choose one of multiple accounts to log in to.
This is admittedly an edge case, but I suspect many PCWorld readers will have multiple Google accounts and this is an issue to be aware of.
LastPass would probably not do well with any accounts that are protected by two-factor authentication too since LastPass doesn't have access to your passcode generator. I did not have a chance to test this issue thoroughly, however.
Despite its few drawbacks, overall LastPass' Auto-Password Change makes it much easier to change your passwords regularly or when disaster strikes. As for Dashlane's new feature, we look forward to trying it out once we get our hands on it.
