Passwords & account security

The lock everyone picks first. Over five hands-on topics you will learn how passwords are really stored, how they get cracked, how to build ones worth trusting, why a second factor changes everything, and how to lock down your own accounts, finishing with a real security audit you can put in your portfolio.

1. 1
