## The basics: passwords
|
|

|
|
|
|
Passwords are the first barrier to accessing data that we want to keep to ourselves.
|
|
|
|
|
|
We use them to read our email, to withdraw cash at the ATM (PIN), to log into our computer, and to access the thousands of digital services we use.

### People are predictable
|
|
|
|
- Statistically some words are used more ofter
|
|
- We tend to use words that are connected to the website
|
|
- <a style="color:red;">In the worst scenario, the password is reused </a>

### Password Cracking
|
|
|
|
There are programs and services that repeatedly attempt passwords based on our predictability, commonly relying on dictionaries to which rules are applied.
|
|
|
|
Note that in targeted attacks, dictionary files are created ad-hoc, taking all the digital material of the target into consideration.

### Password manager
|
|
|
|
Generate random, hard to gues and crack passwords, unique for every website.
|
|
|
|
You need to remember a single password to access the manager.

### What about the master password?
|
|
- Never share it
|
|
- Never write it down
|
|
- Use at least 4 common words, think of an image or story to memorize the password
