Security

Plain-language definitions of Security terms. 2 terms.

• Two-Factor Authentication (2FA)

  • Security

  2FA is an extra layer of security. Besides your password, you also need to prove it's really you — like by entering a code sent to your phone. So even if someone steals your password, they can't log in easily.

• VPN (Virtual Private Network)

  • Security

  A VPN is a tool that helps protect your privacy online. It hides your internet traffic and can make it look like you're browsing from a different place. Handy for public Wi-Fi or streaming shows from other countries.
