Password managers to the rescue

A password manager servers many purposes, all of them helpful. It keeps all your passwords under one encrypted (and password-protected) roof. It generates strong passwords for you and automatically inserts them when you log into different sites. It can even store payment information to simplify online shopping.

Almost all these tools work on the principle that you create a master password for access to your identity vault, and then the password manager fills in individual user IDs and passwords for the sites and apps you use. One benefit of this approach is, because you no longer have to recall the passwords yourself, you can give each site or app a different, complex and hard to remember password.

All your passwords in one place? What if a hacker gains access to your master password? That would leave all your accounts open to plundering. Likewise, if a hacker manages to breach the central vault of the password management company, it's possible that millions of account credentials could be stolen in a single hack.

There are defenses to both these concerns. Most password managers employ multifactor authentication, so access to your credential vault is granted only with both a correct password and a correct authentication code. That code exists only on a device you own, limiting the ability for someone across the world to gain access to your information.
