A compromised password can’t protect you. PassProtect is a Chrome extension that notifies you whenever a password you enter is exposed, giving you the chance to change it.

Data breaches happen all the time, and the result is usually a bunch of usernames and password floating around the web. Attackers use these lists to access accounts, so it’s important to change your passwords after a breach. Most users can’t keep track of it all, however.

Which is where PassProtect come in. Using data from Have I Been Pwned, Troy Hunt’s database of compromised passwords, PassProtect lets you know when a password you use was part of a recent breach.

This tool alone can’t protect you if you’re re-using passwords at multiple sites, which is why you should use a password manager. These help you randomly generate a password for every site, then store the passwords in a way that is easy to access. It’s worth noting that 1Password, one of the best password managers on the market, already compares passwords with Have I Been Pwned, so there’s no need to install PassProtect if that’s your password manager.

Thanks to my friend Matthew Hughes at The Next Web for pointing out PassProtect.
