Dynamic 3D Secure

Set up rules to determine whether an eligible card payment should use 3D Secure authentication.

Dynamic 3D Secure requires additional configuration on Adyen's end. To turn it on, contact Support Team.

When Dynamic 3D Secure is turned on and if you send all the required 3D Secure fields in your payment request, your transactions will go through Dynamic 3D Secure rules.

If you configured a rule to trigger 3D Secure, we will request for 3D Secure 1 or 3D Secure 2 authentication, depending on the version supported by the issuer. For information on setting up 3D Secure, see 3D Secure 1.

To mitigate any effects on conversion, you can configure these rules to determine which payments are sent for 3D Secure authentication, and which are processed without.

If you are using Dynamic 3D Secure for PSD2 compliance, we recommend that you always request 3D Secure authentication for transactions that require SCA. See PSD2 compliance guide.

Configuring Dynamic 3D Secure rules

To configure the rules, go to Customer Area > Risk > Dynamic 3D Secure.

You can configure the following criteria. These can also be combined to create nested rules. For example, you may decide to use 3D Secure for every transaction where the issuing card is from Mexico, has a risk score greater than 70, and a transaction value above $100. 



Issuer country

The country where the card was issued.

Shopper Country

The country of the shopper, based on the IP address submitted with the payment.

Payment Method

The card type (for example, American Express, Visa Platinum, etc. For more information, see PaymentMethodVariant).

Device Type

The type of device that submitted the transaction. You can indicate mobile, desktop, or tablet devices.

The transaction must have device data submitted with it for this feature to work.


The transaction value. When you configure this for a specific currency, the rule will automatically convert to other currencies. For example, a 20 EUR rule will automatically trigger for the equivalent amount in GBP.

Risk Score

Allows the targeting of 3D Secure for only transactions that meet certain risk score thresholds.

If a transaction's risk score is 100 or more, it is always rejected by RevenueProtect and, thus, will not use 3D Secure.

BIN and BIN Range

The first six digits on a credit card. This identifies the Issuing bank of the card. For more information, read Bank Identification Number (BIN).

You can target a set or range of BINs, to use 3D Secure only for transactions from certain issuing banks.

risk rule Trigger Specific risk rules that trigger 3D Secure. By default, this only applies to payments with a fraud score between 1 and 100. Select Trigger on TRUST risk result to turn this on for payments with a score 0 or below.

For each condition met, assign actions to use or drop 3D Secure authentication:

  • Use 3DS - If the condition is met, choose to apply any of the default 3D Secure rules.
  • Drop 3DS - If the condition is met, choose to Never drop 3D Secure authentication or to drop 3D Secure depending on the transaction status:

    • If 3DS directory lookup response U: Drop 3D Secure when authentication is unavailable.
    • If 3DS authentication response N: Drop 3D Secure when authentication has been denied.
    • If 3DS authentication response U: Drop 3D Secure when the card issuer is unavailable.

A few things to keep in mind when configuring Dynamic 3D Secure:

  • Rules are maintained at the merchant level. They will only effect payments for a specific merchant.

  • System-wide rules (for example, that all Maestro payments must use 3D Secure) will override the Dynamic 3D Secure rules.

  • Wherever possible, create several simple rules instead of combining many logic points into a single rule.

  • The sub-components of the rules must comprise an AND statement. If you want to use an OR statement, create a new rule.

  • Rules trigger in order, from first to last.

  • If no rules are triggered, and 3D Secure is available, the transaction will use 3D Secure.

Default 3D Secure rules

Choose from the following possible default 3D Secure rules that you can set up on your account. Depending on your configured rule, we will perform the following actions:

  • Always: Use 3D Secure whenever possible.
  • Prefer no: Do not apply 3D Secure authentication, unless the issuing bank requires it to complete the authorization.

Due to PSD2 SCA mandate, we replaced the Never option with Prefer no. For more information on how Adyen determines when to apply for authentication, read about our Authentication Engine.

Rule configuration examples

Scenario 1

You are experiencing significant fraud in transactions above USD 200 in the US and EUR 250 in Germany. You decide to explicitly focus on applying authentication for high-risk transactions in these regions, and apply 3D Secure whenever strong customer authentication (SCA) is mandated.

The rules you should set up are:

  1. Always use 3D Secure when transaction >= USD 200 AND risk score >50 AND issuing country = United States.
  2. Always use 3D Secure when transaction >= EUR 250 AND risk score >50 AND issuing country = Germany.
  3. Prefer no 3D Secure authentication for all other transactions (default rule).

The last rule ensures that transactions with less than the specified amounts will still trigger 3D Secure if SCA is required. In this scenario, issuing banks in Germany are expected to require SCA as part of PSD2 regulations.

Scenario 2

You are planning on expanding your business in the United States. You have previously used 3D Secure in the UK (where conversion rates are high), and you want to avoid using 3D Secure in the United States. All your traffic is from the UK and US.

Rules you should set up:

  1. Prefer no 3D authentication Secure when issuing country = United States
  2. Always use 3D Secure for all other transactions (default rule).

Only a Prefer No rule is needed since the default action is for transactions to use 3D Secure. With this setup, all UK transactions will use 3D Secure.
