"Authentication Failed" error message

If your bank / card provider is based in Europe, there's a new regulation which requires a "3D Secure" authentication to process most online payments. This includes your Practice Portuguese subscription!

The authentication is the part after you click "Sign Up Now" where your bank displays a pop-up window. Each bank will show something different, but usually they send you a code to your email / text / banking app, or they ask you to complete a security challenge of some sort.
