How To Enable 2FA In Twitch

As Twitch is so incredibly popular, that makes it a target for hackers and scammers. Any platform that counts its users in the millions has the same challenge. The traditional username and password are not secure, so using 2FA, Two-factor Authentication is a no-brainer. This tutorial will show you how to enable 2FA in Twitch.


Two-factor authentication uses two factors, two verification methods, to permit access to an account. You probably already use it elsewhere for banking Gmail, Outlook, PayPal, or something else. You log in using your username and password, and then a code is sent to your phone. Once you enter the code into the login box, you gain entry to your account. That’s two-factor authentication.

It’s an extra step in the login process and does require you to have your phone with you all the time, but who doesn’t have their phone with them constantly?

Enable 2FA in Twitch

In Twitch, you can choose whether to use SMS or an authenticator app to receive your verification codes. However, you can only set up an authenticator app on the Twitch web or desktop app.

Follow our quick tutorials below, and we’ll show you how to enable 2FA on the Twitch web and mobile app.

On your computer:

  1. Using your preferred web browser, visit the Twitch web client and sign in to your account.
  2. Click your profile icon on the top right corner and select Settings to access your Dashboard.

  3. Select the Security and Privacy tab.

  4. Select the purple “Set Up Two-Factor Authentication” button by Security.

  5. Click the Enable 2FA button.

  6. Select your country, enter your phone number, and click Continue.

  7. Enter your password to verify your account.
  8. Enter the 7-digit verification code you received via SMS into the Twitch window.

  9. If you want to use an authenticator app, scan the QR code on your screen with the app and enter the verification code. Otherwise, select the “Skip & Use SMS” option.

If you ever change your mind, you can always disable the 2FA feature whenever you want.

On your mobile device:

  1. Open the Twitch app from your home screen or app drawer and sign in to your account.
  2. Tap your profile icon on the top left corner of your screen.

  3. Head to your Account Settings and select Security & Privacy.

  4. Tap Two-Factor Authentication to start setting up your 2FA.

  5. Enter your phone number and tap Continue. Make sure that your number is in full international format.

  6. Enter the verification code you received through SMS and select Submit.

That’s how you enable 2FA on the Twitch mobile app. If you want to use an authenticator app like Authy, you’ll need to set up your two-factor authentication on the Twitch web app.

How 2FA secures online accounts

Two-factor authentication has been around for a while and is now the default for most banks and financial institutions. Many online stores, game platforms, and other online communities also have the option for 2FA. It’s a simple yet effective way to secure your personal data online.

But how does it protect you?

In an old-style account, your account data was protected by an authentication layer that required a username and password. Both entries needed to be correct to allow access to that account. The challenge is that however long your password might be, bots are powerful enough to crack them in seconds, perhaps minutes if you use a passphrase.

Although the platform needs to have username and password access to allow you to use the system, this also left it open to attack. A brute force or dictionary attack could be launched at the login screen and try literally millions of combinations a minute. Once cracked, your account was open for all to see.

Second factor

When you enable 2FA, you’ll have an extra layer of protection to the login process on your account. Without passing through and authenticating this layer, the system will not allow access to the account. So when someone hacks your username and password, they will not be able to access the account without adding that second factor, the verification code.

They would also need the verification code to send via SMS or your authenticator app. Unless people can also hack your phone or have physical access to your phone, they are out of luck.

As you can see, 2FA isn’t perfect. People with access to your phone can bypass it, but the chances of that happening are a tiny fraction. That, and the fact the system is cheap and simple to use, means we will be using 2FA for a long time yet!
