Privacy: Protecting people’s data and personal information (also called sensitive information)

Security: Protecting people’s devices and the software on them

Two-step verification (also called two-factor verification and two-step authentication): A security process where logging in to a service requires two separate steps or two “factors,” such as a password and a one-time code. For example, you may have to enter your password and then enter a code that was texted to your phone or a code from an app.

Password or passcode: A secret combination used to access something. It may take different forms; for example, you may have a four-digit number-only code that you use for your phone lock and a much more complex password for your email account. In general, you should make your passwords as long and complex as you can while still being able to remember them.

Encryption: The process of converting information or data into a code that makes it unreadable and inaccessible

Complexity: The goal when creating a secure password. For example, a password is complex when it has a mix of numbers, special characters (like “$” or “&”), and both lowercase and uppercase letters.

Hacker: A person who uses computers to gain unauthorized access to other people’s or organizations’ devices and data
