Dynamic 3D Secure

Set up rules to determine which card payments are routed through 3D Secure authentication.

When a payment request includes the browserInfo object, Adyen will determine whether the payment is routed through 3D Secure authentication.

To ensure that you stay compliant, we will always apply 3D Secure if this is required by authentication regulations such as PSD2. To mitigate any effects on conversion, we will not trigger 3D Secure for out-of-scope transactions, or if the issuing bank does not enforce 3D Secure. We will also handle requesting for an exemption whenever applicable.

If you want to have more control over which transactions are processed with 3D Secure, for example if certain transactions are high-risk for your business, you can use Adyen's Dynamic 3D Secure. This lets you set up rules to determine which payments are sent for 3D Secure authentication, and which you prefer to be processed without.

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. With this rule, there will still be transactions that don't go through 3D Secure authentication, for example, when the issuer doesn't support 3D Secure yet, or when the card isn't enrolled.
  • Prefer not: Do not apply 3D Secure authentication, unless the issuing bank requires it to complete the authorisation. We recommended that you use this setting if your first priority is to prevent 3D Secure as much as possible.

Due to PSD2 SCA mandate, we replaced the Never option with Prefer not. For more information on how Adyen determines when to apply for authentication, read about our Authentication Engine.

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 check Each risk rule that you select will trigger 3D Secure.
By default, this only applies if the rule has a positive fraud score. If you also want rules with a negative fraud score to trigger 3D Secure, check the Trigger on TRUST risk result check box.

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.

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 only for issuing banks that require it.

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 not 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 the issuing bank requires 3DS. In this scenario, issuing banks in Germany are increasingly expected to require 3DS 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 not 3D authentication Secure when issuing country = United States
  2. Always use 3D Secure for all other transactions (default rule).

Only a Prefer not rule is needed since the default action is for transactions to use 3D Secure. With this setup, all UK transactions will use 3D Secure.
