How can I authorise online transactions with Mastercard SecureCode®?

Mastercard SecureCode® is a service that gives you increased security when buying something online. The service will send an SMS to your registered phone number with a one-time password, which you’ll need to enter to approve your transaction.
This makes sure that only you can complete the payment.
You can make payments at any online store with or without the Mastercard SecureCode® logo – but keep in mind that this service won’t show up every time you shop online, only on some occasions.
The process is simple:

1. Buy something online at any store
2. Use your Monese card to pay
3. A pop-up box will appear with our Monese logo displayed, asking for your one-time password
4. You’ll receive an SMS with your one time password to the mobile phone number you'e registered with us
5. Enter the one time password to approve your purchase
6. Your transaction will go through!

If you don't receive the SMS with your one-time password, you can request another one. From there, you only have 15 minutes to enter it, after which you’ll need a new one.
You can also change your phone number in the Monese app if you need to."
