My LastPass extension just warned me I was re-using my Master Password elsewhere. How?

This is a security feature implemented to help prevent phishing and only works on machines with the LastPass extension installed that you have previously logged in from. This feature takes action whether you are logged in to the extension, or not.

Your master password is a key part of your security. That means that whatever you choose, should be unique to LastPass. Because once you share it with another website, were that website to ever have a security incident or were you to be lured into a phishing attack, you could unknowingly reveal your master password. Though we have other protections in place to protect your account, this significantly reduces the security of your vault and everything you've stored in it.

LastPass will detect if you enter your master password on a non-LastPass page and pops a strong warning, even before you submit it to the page.* You will know immediately that your master password may have been compromised and can change it.

---

How do you know my master password to detect it?
We use a hash of the master password and compare that with a hash of entered text on the webpage, we run it through the same local hashing PBKDF2 rounds you've chosen for your account so the offline attacking is limited in the same way as your local copy of the vault.

But doesn't this mean that, should someone compromise my computer, they could get my master password?
If your computer is compromised, LastPass (or any other software, including all existing antivirus) cannot protect you. However, keeping a clean machine and avoiding behaviors that could lead to malware are also key to protecting your device and your LastPass account.
