Tells you when you're on a site that stores your passwords in plaintext
Too many sites store sensitive information like passwords in plaintext. This leaves your password vulnerable to anyone with access to the site, from the site's developer to a hacker. Thankfully, Plain Text Offenders Alert stops you from giving your password to many of these sites. By using plaintextoffenders.com's constantly updated database of thousands of sites, Plain Text Offenders Alert notifies you if the site is known to be unsafe.
Disclaimer 1: Plain Text Offenders Alert is not associated with plaintextoffenders.com, it uses their publicly available database.
Disclaimer 2: Plain Text Offenders Alert does not have a list of every single insecure site, this would be impossible. It lowers, but does not stop, the chance of you giving your password to an insecure site.

The code is available at https://github.com/klinskyc/PTOAlert. If you have an issue, feature request, or code changes, Github is preferred to the Chrome User Feedback (although I'll check both).
