Transcript

A strong password is one of the best ways to prevent unauthorized access to your accounts, files, and devices and to protect yourself from someone stealing your identity or your money.

In this lesson, you discovered how a hacker guesses passwords using a dictionary attack.

To do this, you wrote ten pretend passwords, then launched a dictionary attack on yourself using functions in Google Sheets.

You had a list of five-thousand common words for your dictionary attack.

But there are actually hundreds of thousands of words in the English language.

A hacker using an automated computer program could try all of them -- and countless variations -- in a real dictionary attack.

Use the tools and strategies from this lesson to stay safe by always using secure passwords for each account.

The best passwords are: memorable to you, but difficult for someone else to guess, at least eight characters long, and a mix of uppercase and lowercase letters, symbols, and numbers.

In addition, the best passwords are: never used for multiple accounts, never written down, stored in a trustworthy and secure password manager and combined with two-step verification.

Great work!

Keep using the strategies you learned in this lesson to secure all of your passwords and keep yourself and your accounts as safe as possible.
