How to Make Sure Your Passwords Haven't Been Stolen
In this age of hackers, data breaches and malware, Lifehacker's put together a list of online resources that can help you find out if your online passwords are still safe. Take a look at a few of their favorites:
Google’s Password Checkup extension. If you use Chrome, this extension will monitor when you log into your sites and find out if it has been previously leaked in a data breach.
Have I Been Pwned. This one is easy and free for the initial search. Just go to their site, enter your email address, and you'll get a warning if your email has ever been involved in a breach.
Firefox monitor. This service is basically a re-skinned version of Have I Been Pwned, but you may prefer it if you are a Firefox browser user.
1Password. This is a paid password manager, but also gives you access to its Watchtower feature, that is slightly more robust version of Have I Been Pwned.
Hasso Plattner Institute’s Identity Leak Checker. This isn't an active monitoring solution, but if you provide your email, they will send you a report if your address is linked to any known data breaches.
Credit Karma. This company is better known for it's credit-monitoring services, but it also offers free identity monitoring.
