This week saw the release of a new service from security researcher Troy Hunt, Pwned Passwords, which lets you check your passwords against a database of more than 500 million passwords to see if any of yours are compromised. And though this tool was just released, the folks over at AgileBits have already integrated it into 1Password.com accounts for subscribers. With the click of a button, you can check to see if a particular password is in the database, letting you know if you need to change it.
Here's how you use 1Password's new Pwned Passwords integration.
A note on security
As AgileBits notes, sending your password off to be checked makes it inherently less secure. But working with Hunt and a team at Cloudflare, they have been able to devise a method of checking passwords without compromising their security. This is especially good news if your password is not in the database.
Here's how 1Password and Pwned Passwords keep your passwords secure when you go to check them:
How to use 1Password.com to see if your passwords are compromised
- Sign in to your 1Password.com account through your web browser of choice.
- Click Open Vault on one of your vaults.
- Click on a vault item to see its details.
- On your Mac keyboard, enter Shift-Control-Option-C (don't use the hyphens), or Shift-Carl-Alt-C on Windows to activate the tool.
- Hover your cursor over your password.
- Click Check Password. You'll get the "Oops, this password was found" or "Not found, way to go. :)" depending one whether or not your password is in the database.
For the moment, you'll need to run a check on each vault item individually, as there is no batch password checking option. Also, note that this is only for 1Password.com memberships. But while this is the case right now, AgileBits plans on adding this integration into the Watchtower section of its 1Password apps so any compromised passwords you might have will be right there in the app for you to see.
