if you only set the inquiry password but not the consumption password, it is unnecessary to spend anywhere.

only if you have set a consumption password.

if the consumption password is not set, online consumption is the same, just enter the inquiry password.

a credit card has two passwords, one is the inquiry password and the other is the consumption password.

if there is any setting, you can call your credit card center to find out. There should be a phone number on the back of the card.
