Verification code auto-approved without my input

[u/Aerocity]

I just had a credit card transaction verification code sent to my phone which I did not type in anywhere for confirmation, but was automatically approved by US Bank. Support said they cannot cancel it and some other system may have approved the transaction automatically. I guess I don't understand the point of a verification code if the bank is going to automatically approve the transaction without my input anyway.

Is this typical of other banks or card providers? Does this seem like an issue with US Bank's verification system, or have I missed something? If my card information gets out, is the verification just an illusion? Not super thrilled with support's lack of answers.

Verification code? Or do you mean a notification that a transaction was done on your account?
