PASSWORD MANAGERS ARE the vegetables of the internet. We know they’re good for us, but most of us are happier snacking on the password equivalent of junk food. For seven years running that’s been “123456” and “password”—the two most commonly used passwords on the web.
The problem is, most of us don’t know what makes a good password and aren’t about to remember hundreds of them every day.
If you can memorize strong passwords for hundreds of sites, by all means do it. Assuming you’re using secure passwords—which is, first and foremost, shorthand for long passwords—this is the most secure, if slightly insane, way to store passwords. It might work for Memory Grandmaster Ed Cooke, but most of us are not willing to put in the effort. We need to offload that work to password managers, which offer secure vaults that can stand in for our faulty, overworked memories.
