As another comment already pointed out, you are probably seeing your card issuer's risk-based 3D Secure system in action. If your system (IP address, location, user-agent) and/or the transaction (merchant, sector, amount) look familiar enough, some issuers let you skip the password/TAN entry. If they are doing it right, that's a good thing. |
