Turning on Two-Factor Authentication – Facebook Messenger

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

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.

Turning on 2FA for Facebook Messenger

By setting up 2FA for Facebook Messenger, you'll be asked to enter a special login code or to confirm your login attempts each time you try to access Facebook Messenger from a mobile device Facebook doesn’t recognise. Facebook will also send you alerts whenever someone tries to log in to your account.
