At Hostinger, we protect your payment information by using 3-D Secure verification. If you encounter an error or a failed payment authorization related to 3-D Secure, here are the possible reasons:
Your browser or device has a pop-up blocker that prevents the 3-D Secure page from opening.
If you're overseas, your bank may be sending a netcode SMS to a different phone number than the one you're using.
Your bank may not be enrolled in the 3-D Secure verification program, or your card may not support international and online payments.
If you face this error, try making the payment again using a different browser with all browser extensions disabled.
If the issue persists, please contact your bank or card issuer to confirm if they support 3-D Secure verification and if your card can be used for international and online payments.
