You do not know the merchant
If you do not know the merchant and you do not believe that you have made such a purchase, please refuse the authentication in LuxTrust Mobile. If you receive a call and you are asked to authenticate a payment or transaction via LuxTrust Mobile, please do not follow such instructions, but hang up and immediately call Spuerkeess Direct on (+352) 4015-1.

You know the merchant
If you know the merchant and you have a business relationship with them (e.g. subscription, online booking), then it is an authentication that is initiated directly by the merchant who is asking you to approve it – to finalise or extend a subscription, for example. This allows you to confirm the transaction, without having to take any further steps. Please only approve such transactions if they seem trustworthy and correct to you.
