What Is Two-Factor Authentication?

Two-factor authentication is an extra layer of security used when logging into websites or apps. It requires users to enter both a password and a code that is sent to their phone. This makes it more difficult for hackers to access accounts, as they would need both the password and the code.

Key Points

• Two-Factor Authentication is an additional layer of security that can be used to protect online accounts.
• When using Two-Factor Authentication, a user will need to provide two pieces of information to log in – typically something they know (like a password) and something they have (like a code sent to their phone).
• Two-Factor Authentication can help reduce the risk of account hijacking and data breaches, as it makes it much harder for attackers to gain access to accounts.
• Not all online services offer Two-Factor Authentication, but it is becoming more common – so be sure to check if it’s an option for any important accounts you have!
