I’ve mentioned before that I use 1Password as my password manager of choice. Last week, AgileBits, the product’s developer, rolled out a proof of concept to check and see if one of your passwords had been compromised by checking them against Troy Hunt’s Pwned Passwords site.

If you are a 1Password member, you should check out the blog post to see how they’re accomplishing this in such a way that your password never has to leave your device to be checked against the database.
