Turning on Two-Factor Authentication – Microsoft Accounts

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

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.

Setting up 2FA for your Microsoft Account on your computer

Once you turn on 2FA for your Microsoft account, you’ll get a security code sent to your email, phone or authenticator app every time you sign into an unknown device. When it is turned off, you will get notifications periodically or when there might be a risk to your account’s security.


1.        Sign in to your Microsoft or Outlook account. You can sign in or create an account by visiting Microsoft.
