If you receive a 3D Secure authentication message, it means that your bank requires additional security verification for online transactions. This verification process helps protect your card from unauthorised use.

The delay in resolving the 3D Secure authentication issue often stems from not having 3D Secure for your credit card enabled, resulting in a rejection from the bank.
