All you need to know about two-factor authentication via text message
What is two-factor authentication via text message?
Two-factor authentication is a security process that protects your Miles & More account against unauthorised access.
Whenever you want to change the personal information in your profile, you’ll be asked to enter a time-limited code that will be sent to your mobile phone as a text message. This procedure makes your personal information more secure.
What are the advantages of two-factor authentication via text message?
Confirmation via text message protects your personal information from being modified by unauthorised persons. If criminals acquire your login details, they can’t use them to modify your information because you’re the only one who will receive a text message code on your mobile device.
Do I have to use two-factor authentication?
If you’ve previously set up two-factor authentication via text message, you must also authenticate any change to your personal information using a text message code. If you haven’t previously set up two-factor authentication via text message, this input is not required. You can now set up two-factor authentication via app.
How does two-factor authentication via text message work?
Whenever you wish to perform an operation requiring two-factor authentication, you’ll be asked to verify your identity. Click on the “Request code” button. You’ll then receive a six-digit code as a text message. Enter it in the “Authentication code” field.
I’ve entered the code, but it’s not working. What can I do?
You can re-enter the code. However, for security reasons, the number of entry attempts is restricted. If you enter it too many times, you won’t be able to enter another code for 30 minutes. Try again once this period has expired.
I haven’t received the code. What can I do?
Request a new code. If, after several attempts, you have still not received the code as a text message, please check the following.
- Is the phone number stored in your Miles & More account for two-factor authentication correct for the device you are currently using?
- Are you connected to a mobile network (to be able to receive text messages)?
- Are incoming text messages disabled in your mobile device’s settings?
- Is your mobile device in “Do not disturb” mode?
You can also restart your mobile device and check whether the text message subsequently arrives.
I can’t receive text messages at the moment. What can I do?
Try again later when you can receive text messages. If you continue to have difficulties receiving text messages, please call us.
I can’t receive codes by text message at all. What can I do?
Please call us.
Can I get the code sent to a different mobile phone number?
You must change the mobile phone number stored in your personal information to do this. However, you can only make this change by verifying your identity using two-factor authentication on the old mobile phone number.
- Step 1: log in to your Miles & More account.
- Step 2: in your account, go to “Profile” and click on “Personal information”.
- Step 3: click on “Change mobile phone number”.
- Step 4: you’ll now be asked to verify your identity using two-factor authentication.
- Step 5: request a code. This will be sent to the old/previous mobile phone number.
- Step 6: once you’ve successfully identified yourself, you can change your mobile phone number. From this point on, the two-factor authentication code will be sent to this (new) mobile phone number.
If you no longer have access to your old mobile phone number, please call us. We can take your new mobile phone number so that you can start the setup process again.
I don’t have my mobile device anymore (lost or stolen), and I no longer have the mobile phone number. What can I do?
Please call us.
Will two-factor authentication cost me anything?
No. Two-factor authentication is free of charge provided that your mobile phone provider does not charge you for receiving text messages. If you’re abroad, roaming charges may apply.
How does two-factor authentication via text message differ from two-factor authentication via app?
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 your miles, Points, login details and personal information, etc. Instead of receiving a code via text message, a code is generated in an authentication app and must be entered every time you log in to your Miles & More account or Lufthansa Group websites and apps. You’ll find everything you need to know about the benefits of two-factor authentication via app here.
How can I switch from two-factor authentication via text message to two-factor authentication via app?
Go to your profile in your account and click on “Personal details”, or click here.
In the blue box entitled “Improved security settings for your account”, click on “Set up now”. The setup assistant will guide you through the process. You’ll also find detailed information on every step under two-factor authentication via app.
