Step-by-Step Guide - Turning on Two-Factor Authentication - Twitter

First published October 2019


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

What is two-factor authentication?

Two-factor authentication (2FA) is a process 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 them 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 them 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.
