I always have my debit and credit cards from my bank turned off. If I’m going to use them, I activate them while I’m standing there, let the charge go through, and turn the card off immediately.
I’m glad I did that because I got notification, several months back from my bank one day someone tried to use the card for a purchase of a guitar and related equipment to the tune of $500 which was denied because the card was off. The bank let me know. the card was cancelled and a new card issued.
You have a bank account accessible from the internet? I hope it is through an app, and disabled via browser, at least that provides some protection.
