LastPass just announced a new feature for the password manager that automatically changes your password for sites when a hack is reported.
All you need to do to use the new feature is log into your LastPass account, head to the site you want to set up Auto-Password change for, click Edit, and then click the "Change Password Automatically" button. Right now, around 75 popular sites are supported, including Facebook, Twitter and Amazon.
Once it's set up, LastPass will automatically change your password for you. It does this locally on your machine by opening up a new tab, logging in, creating a new password, then submitting that change to the site in question.
LastPass's announcement comes the same day as rival password manager Dashlane introduced a similar feature. This isn't a feature you could easily knock out in a few hours, however -- it seems likely that both have been working on this option, though the LastPass rollout may have been fast-tracked following Dashlane's launch.
