How Do I Set Up Two-Factor Authentication?

Two-factor authentication (2FA) adds an extra layer of security to your account. Besides your password, you’ll enter a 6-digit code from an app or your email. Here’s how to set up 2FA quickly and easily.

Overview

With two-factor authentication, you add an extra layer of protection to your account against unauthorized access. After activation, you’ll always be prompted to enter a 6-digit code in addition to your password when logging in. You can choose to receive this code via an authenticator app (like Google Authenticator) or by email – or activate both options at the same time.

Accessing the Function

To find the setting, go to your Account Settings and open Personal Settings. Then scroll to the Two-Factor Authentication section.

Step-by-Step Guide

Step 1: Choose Your Method

In the Two-Factor Authentication section, go to Select Authentication Method. Here you can choose between Authenticator App and Email.

  • With the Authenticator App, you set up 2FA through an app like Google Authenticator, which even works offline.
  • With Email, you’ll receive a code sent to your registered email address during login.

Step 2.1: Activate Authenticator App

Switch the toggle under the Authenticator App tab to Enable App Authentication (ON). A QR code will appear – scan this with your authenticator app. If scanning doesn’t work, you can enter the secret code shown next to the QR code manually into your app. Use Copy to Clipboard to quickly copy the code. After you’ve added it in your app, click Save. A dialog will then appear where you enter the 6-digit code generated by your app to confirm setup.

Important: Make sure you enter the code from your authenticator app correctly – otherwise, you’ll see a message saying, “The entered one-time password was incorrect.” If you already have another method enabled, you may need to remove it first.

Step 2.2: Activate Email Authentication

Select the Email tab and switch Enable Email Authentication to ON. Your registered email address will appear. After clicking Save, a 6-digit code will automatically be sent to this address. Enter the code in the pop-up window to confirm setup.

If you don’t receive a code, be sure to check your spam folder. When logging in, if you need a new code, simply click “Didn’t receive a code? Send new code.” under the “2FA Authentication” section.

Step 3: Verify Completion

Once set up, the dialog will close automatically. You’ll now see your active 2FA methods listed in the Authorized Devices area, such as Authenticator App or Email: your@email.com. You can disable any method at any time by clicking Remove.

You can use both methods in parallel. When logging in, you can choose which code to use for authentication.

Step 4: Logging In With 2FA

Sign in as usual; if 2FA is enabled, the 2FA Authentication page will appear. Enter your 6-digit code from your app or email into the six fields and click Submit. If you’re using email, you’ll also see the option “Didn’t receive a code? Send new code.” to request a new code.

If you enter the wrong or expired code, you’ll see a message saying “The entered one-time password was incorrect.”

Settings & Options

  • Under Authorized Devices, you’ll find a list of all currently active 2FA methods, which you can disable any time with Remove.
  • In the Select Authentication Method section, you can freely switch between Authenticator App and Email, or use both at once.

Limitations & Special Notes

  • Email codes are only valid for a few minutes (about 5 minutes). After they expire, just request a new code.
  • If you disable a method, it’s removed immediately – whether by the ON/OFF toggle or Remove.
  • Incorrect entries are always returned with a clear error message.

Tips & Best Practices

  • For maximum security and reliability, we recommend using the Authenticator App. This works even if you don’t have email access or internet connection.
  • It’s best to enable both methods (app and email). This gives you a fallback in case one device or service is unavailable.
  • Never share the secret code that’s displayed during setup. Store it securely.
  • Check your spam folder if you don’t get the email.
  • Avoid enabling two-factor authentication on shared email accounts to prevent misuse.
