All you need to know about two-factor authentication via app

The two-step login process provides additional protection against unauthorised access for your account and therefore your miles and Points. Even if criminals were to obtain your login details, they could not log in to your account without the code from your saved device.

If you want to make changes to your personal details, you need to use two-factor authentication. We recommend setting up two-factor authentication via app, especially if you haven’t yet activated authentication via text message, as this offers a higher level of security. Your Miles & More account will then enjoy optimum protection against unauthorised access.

• Step 1: log in to your Miles & More account.
• Step 2: go to “Security” in your Miles & More account.
• Step 3: in the white box “Protect your account with two-factor authentication”, click on “Set up now”.
• Step 4: download an authentication app. We recommend downloading a free authentication app such as Microsoft Authenticator (available in the App Store for iOS) or Google Authenticator (available in the Google Play Store for Android).
• Step 5: a) if you’re using a computer for authentication, scan the QR code from your Miles & More account with your authentication app.
• Step 5: b) if you’re using your mobile phone, copy the alphanumeric code from Miles & More and enter it in your authentication app.
• Step 6: once you’ve completed the setup, your two-factor authentication via app is ready to use and your account has additional protection.

Once you’ve entered your login details for your Miles & More account or the Lufthansa Group websites and apps, you’ll be asked to enter a six-digit code. Open your authentication app to see the code. Enter this code in the input field when you log in.

Open your authentication app again, and enter the code shown in the authentication app in the third step of the login process. The code is time-based and expires after a certain time. If the code doesn’t work even after entering it several times, please check if you’re also using the authentication app for another system and if you’ve selected the code for Miles & More or your Travel ID account.

For security reasons, the number of entry attempts is restricted. If you enter an incorrect code too many times, you won’t be able to enter another code for 30 minutes. It will not be possible to log in during this time. Try again once this period has expired.

Try closing the authentication app and opening it again. If that doesn’t work, please contact your authentication app’s customer service. Here you’ll find further information and assistance for Microsoft Authenticator and Google Authenticator.

You can contact the Service Centre to reset two-factor authentication via app. If this is the case, please call our Service Centre.

No. If you use a free authentication app, two-factor authentication won’t cost you anything. We recommend the Microsoft Authenticator app or Google Authenticator.

If you opt for two-factor authentication via app, your miles, Points and the data in your Miles & More account have additional protection.

Two-factor authentication via app offers greater protection for your account. While two-factor authentication via text message protects against unauthorised changes to personal information in your profile, two-factor authentication via app protects against access to your account and therefore safeguards your Points, login details, personal information, etc.

Instead of sending a code via text message, two-factor authentication via app generates a code in an authentication app. This code must be entered every time you log in to your Miles & More account or to Lufthansa Group websites and apps.

If you’ve been using authentication via text message, you can easily switch to the app method at any time. To do so, go to your Miles & More account and select “Security”. Then click the “Increase security now” button in the white box labelled “Improved security settings for your account”. The setup assistant will guide you through the process.

If you want to change your mobile device or use a different authentication app in the future, you can reset your mobile device or authentication app yourself in your Miles & More account and register a new second factor. This is only possible if you still have access to your current mobile device or authentication app. Otherwise, please call our Service Team.

To register a new second factor, first log in to your Miles & More account. Then go to “Security” in your Miles & More account. In the white box labelled “Change mobile device or authentication app”, click “Change now”.

Follow all the steps using your new mobile device or new authentication app to reset your second factor and to connect a new device or app. If the registration of a new second factor is not completed correctly, you will be logged out for security reasons. You’ll then only be able to log in after registering a new second factor.

Once you have successfully re-established two-factor authentication, you’ll only be able to log in to miles-and-more.com, the Miles & More app and Lufthansa Group websites and apps with the new second factor.

When using your new second factor, it may be helpful to remove your former second factor from the authentication app.

Once you’ve set up two-factor authentication, the next time you log in you’ll be asked whether the browser or app you’re using is trusted. If you confirm this, the browser or app you’re using to log in will be saved as trusted. You can save up to five browsers/apps as trusted at any one time. Please note that the use of cookies must be activated in your browser.

If you’ve saved a browser/app as trusted, you’ll no longer need the authentication app the next time you log in with this browser/app. This gives you easier access while guaranteeing security. When you log in with a new browser or app for the first time, you’ll always need your authentication app to log in.

• Click on the pencil under “Security”.
• Now you’ll see a list of your trusted browsers and apps.
