Learn About Password Security
We begin with a brief lesson on password security. I want to keep it short, so I won’t go into tremendous detail about encryption algorithms and cryptographic mathematics, and I’m going to do a bit of hand-waving when we get to the geekier concepts (and refer you to Appendix C: Calculate Password Strength if you’re genuinely interested in the details). But I think it’s important to have a basic grasp of the principles of password usage so you know what you’re up against, and why simple-sounding solutions are often extremely unwise.
And, even if you were well-versed in password security basics a few years ago, you should be sure to read about Multi-Factor Authentication, which has become increasingly important.
