What is two-factor authentication?
Two-factor authentication (2FA) is a procedure that typically requires a combination of something a user knows (pin, secret question) and something a user has (cards, fingerprint) in order to access a program or operating system.
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, specifically 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.
