Support autofilling credit card info

Note that credit card info is encrypted and relies on storing a key in the session secret service by default.

Well, in general, in every bank, in every application there is such a function. I find this to be very handy. But sometimes it is a danger to a person. It is better to enter all the data yourself. There are many autocomplete forms. When I took out a loan, I was also offered autofill in the future. I then found the best business line of credit, used https://fitmymoney.com/best-business-line-of-credit/ for that. I refused this function since it is still a loan, and suddenly someone hacks something and uses my profile, and everything is already filled there. You can do this only at your own peril and risk.
