What is 3D Secure (3DS)?

3D Secure is an additional layer of security for online credit card transactions used by card networks, meant to reduce the risk of fraud. Many regions of the world support 3DS to comply with Strong Customer Authentication (SCA) mandates. All Brex cards are compatible with 3DS protection globally.

How 3DS works

When an online transaction uses 3DS, you’ll be asked to verify the transaction on the merchant website at checkout.

You’ll receive an email and/or SMS with a one-time password (OTP) to complete the verification. Input the OTP into the field labeled Confirmation code and click Confirm.

Once the verification is successful, you’ll be returned to the merchant website to finish the checkout process.

If you didn’t receive the confirmation code via email address or SMS, please try requesting a new code. If you’re still having issues, please chat with Brex Support  through your dashboard.
