From “How I became a password cracker” at Ars Technica:
Watching your own password fall in less than a second is the sort of online security lesson everyone should learn at least once—and it provides a free education in how to build a better password.
I admit it: I used to practice the lazy habit of re-using weak passwords on multiple sites. Then I read too many stories like these and got religion. Read them for yourself and then consider whether turning on two-factor authentication and using an app like 1Password is worth the hassle.
For the longest time, precautions like these weren’t worth my time and effort. But now they seem like very cheap insurance.
