1. Introduction to Create and Safeguard Passwords

Playback Speed:

A password is a secret combination of letters, numbers, or symbols.

Many devices, apps, websites, and games require you to have a username and password.

Your username and password are unique to you, so they can be used to prove your identity -- in other words, that you are really you.

In this lesson, you will discover why secure passwords are so important to protect you and your identity.

You will use a spreadsheet to practice creating passwords and discover the best ways to make and keep them safe.

This lesson uses Google Sheets, but you could apply these skills and concepts in any spreadsheet application.

To work on this lesson, sign in to your Google account.

Open a new tab in your browser, and navigate to Google dot com.

If you are not signed in, do so now.

If you do not have a Google account, pause the video and create one now.

Then, open Google Drive and create a new spreadsheet.

Give it the title Dictionary Attack.

And rename sheet one Fake Passwords.

Spreadsheets are comprised of numerous cells.

A cell is a place where data is entered.

Cells are named by the corresponding row and column.

In cell A one, type Passwords, and make it bold.

Now, quickly brainstorm ten pretend passwords that you think you could easily remember.

Do not use any passwords that you actually use in real life.

Type your ten pretend passwords in separate cells beneath the Passwords header.

Each password should be at least eight characters long.

If you choose a word that is shorter, add something to it.

When you have finished adding your ten passwords, move on to the next video to see how someone might guess your passwords and endanger your security.

Now, it’s your turn: Open a new spreadsheet, and title it Dictionary Attack, Rename sheet one Fake Passwords, Create a column called Passwords, And type 10 pretend passwords.

Make sure they are at least eight characters each and you could remember them easily.
