Password Manager Security

The internet has become ubiquitous in our everyday life. There are billions of people who use the internet every day, and that number is only increasing. Companies like Facebook, Google, and Amazon boast hundreds of millions or even billions of users. But most people don’t limit their internet usage to a few large sites; in fact, the average American has about 200 different accounts on various websites [1]. This large number of accounts corresponds to a similarly large number of passwords; it’s clearly desirable to use a different password for each service to keep any successful attacks localized, and various password restrictions will force at least some differences between passwords. Since it’s not reasonable to remember hundreds of distinct passwords, it’s common to use some sort of password manager to keep track of them. However, many people may understandably have some hesitation in providing all of their passwords to a password manager.
