Both my Danish and British accounts send an SMS for some purchases, usually only larger ones. I have to type it into a box on a form.

They used to use a password, but that risks people putting their bank password into some dodgy shopping site.

Bit of a late reply but almost all companies use something called a digipass, you insert your card and input a challenge code and your pin. https://i.imgur.com/10OChcv.jpg
