3D Secure code: which PIN do I use for an online purchase?

What is your card PIN code and how do you use it?

On some online payments, you may be asked to enter a validation code. At KeeCash this is your card PIN code (4 digits), used as part of 3D Secure (strong authentication).

What is 3D Secure?

3D Secure is a security step used by some websites to validate a payment.
It checks that you really are the owner of the card before the transaction is completed.

Which code should I use?

When this check is requested, you must enter: the PIN code of your KeeCash card (4 digits)

Do not mix up the codes

Several codes can be requested during a payment. Here is the difference:

PIN code (4 digits)

→ used for 3D Secure (validating the payment)

CVV / CVC (3 digits)

→ requested on every payment

KeeCash password

→ used only to log in to the app

Where do I find your card PIN code?

You can see your PIN code directly in the app:

Go to My cards
Select your card
Tap the 👁️ icon to reveal the code

When is this code requested?

This purchase PIN code may be requested when:

the website triggers a 3D Secure check
the payment needs extra security
the amount is considered sensitive
the cardholder needs to be verified

Not every payment needs this step.

Important note: never share your PIN with anyone. We will never ask you to give your PIN by email or by phone. This is in place to protect your funds and your identity.
