In my opinion, all companies should (be able to) offer an alternative means of
authentication, if only for reasons of disability / accessibility, where not
all people are able to use a screen captcha / smartphone / telephone / etc.

For example, in Germany, Deutsche Bank switched a few years ago from using
One-Time Pad Transaction Authentication Numbers to presenting a QR-code style
(it's different, but it's the same idea) image on the screen when you're
performing a transaction, and you either need a smartphone with a camera and
the DB app installed, to read the code and show you the numbers on the
smartphone screen, which you then type into the web page you are doing the
transaction on, or you do the same thing with a specialised device which you
buy from DB for €15 instead of using the smartphone and app.

Neither of these works effectively for a blind user, so there is an (almost
totally un-advertised) alternative where they will send a text message instead
(knowing that blind people can generally manage to receive and read a text
message by one means or another).

It's still not entirely ideal, but it is at least an alternative, but you have
to really ask to find out that it even exists.
