Two-Factor Authentication (2FA) is an extra layer of security used to ensure that people trying to gain access to an online account are who they say they are. First, a user will enter their username and a password. Then, instead of immediately gaining access, they will be required to provide another piece of information, such as a code sent to their phone.

A Virtual Private Network (VPN) allows you to create a secure connection to another network over the Internet. VPNs can be used to access region-restricted websites, shield your browsing activity from prying eyes on public Wi-Fi, and more. A VPN encrypts your internet traffic and disguises your online identity, making it harder for third parties to track your activities online.

A strong password is at least 12 characters long, includes a mix of letters (both uppercase and lowercase), numbers, and symbols.
