Prevent Pwned Passwords

SUMMARY

Prevent Pwned Passwords helps make sure you don't use any password that's known to have been part of a data breach. If you try to use a password that's known to have been compromised, you'll get an alert. You can choose to run it whenever you enter a password on any site, whenever you enter a password on a "Create Account" page, or only when you choose to check a password from a context menu. You can also whitelist sites, giving you greater control over what passwords are checked. This extension hashes your password and securely checks that hash against a database of hashes known to be breached. If it's been involved in a past breach (of any account across hundreds of sites), it notifies you so you can change your password. Note that the only data ever transmitted is a password hash. We never send a clear-text password or any identifiable information like a username or a URL. This extension uses the Have I Been Pwned service.

The latest version of Prevent Pwned Passwords is available on the Chrome web and is currently being used by 115 active users. The initial version was launched on 2017-10-28.
