PC World has a review of password managers (they like Lastpass), but perhaps more important, they provide a list of reasons to adopt one of these products:
- Password generation: You’ve been reminded ad nauseam that the strongest passwords are long, random strings of characters, and that you should use a different one for each site you access. That’s a tall order. This is what makes password generation—the ability to create complex passwords out of letters, numbers, and special characters—an indispensable feature of any good password manager. The best password managers will also be able to analyze your existing passwords for weaknesses and upgrade them with a click.
- Autofill and auto-login: Most password managers can autofill your login credentials whenever you visit a site and even log you in automatically. Thus, the master password is the only one you ever have to enter. This is controversial, though, as browser autofill has long been a security concern, so the best managers will also let you toggle off this feature if you feel the risk outweighs the convenience.
- Secure sharing: Sometimes you need to share a password with a family member or coworker. A password manager should let you do so without compromising your security.
- Two-factor authentication: To an enterprising cybercriminal, your password manager’s master password is as hackable as any other password. Increasingly, password managers support multi-factor authentication—using a second method such as a PIN, a fingerprint, or another “trusted device” for additional verification—to mitigate this risk. Choose one that does.
- Protection for other personal data: Because of how frequently we use them online, credit card and bank account numbers, our addresses, and other personal data can be securely stored in many password managers and automatically filled into web forms when we’re shopping or registering an account.
