Lesson 2
The Password Manager
See how a vault keeps passwords the company can’t read, why it refuses lookalike sites, and how to move in without locking yourself out.
A locked box with a copy in the cloud
You have dozens of accounts and can’t remember dozens of different random passwords. Nobody can. A password manager does three jobs for you: it remembers them, it makes them up, and it fills them in only on the site they belong to.
It keeps them in a vault: think of a locked box. The box is locked on your own phone or laptop, with a key made from your master passphrase, before a copy goes up to the company’s servers so your other devices can have it. In the design the main managers describe, the company holds the box but never the key. That’s why the next lesson is about the one passphrase you must choose well. Managers differ in the details, so read how yours handles sign-in and recovery before you rely on it, including any emergency kit: a sheet of sign-in and recovery details, offered by many managers, that you print and keep safe.
