This step-by-step guide shows you how to turn on two-factor authentication (2FA) on your computer and mobile devices for Gmail.

Why is it important to turn it on?

Using 2FA to access your favourite programs provides enhanced security to traditional usernames and passwords. The multiple layers of authentication increase confidence that the user requesting access is actually who they claim to be i.e. you.

Where do I turn it on?

Where to turn on 2FA within a program depends on each program. However, the steps are universally simple and somewhat similar. Icons and language may differ slightly depending on the program, or device you are using.
