Kurt Knutsson the CyberGuy explains why two-factor authentication will improve security on all your devices, and shows you how to enable it on your devices.

To address the ever-rising security risks, many websites now offer two-factor authentication (2FA), also known as multi-factor authentication, as an added layer of user protection.

Two-factor authentication adds an additional layer of security to your online accounts, providing more security than a password alone.

This is known as two-step verification rather than two-factor authentication because even though two questions are asked, the second factor of authentication isn't different from the first.

How does two-factor authentication make your account more secure? The idea is that you're adding a confirmatory step to your sign-in attempt.

Two-factor authentication is a second layer of security that can better protect your most important online accounts.

While two-factor authentication can be time-consuming to set up for every account, it's relatively straightforward to set up and use, and well worth the effort.

Two-factor authentication can also use something you are: biometrics, requiring a fingerprint, for example.

Two-factor authentication and two-step verification are two common methods of ensuring not only a more secure connection but also protection against unwanted use or access.
