I despise sites that disallow pasting into fields.

Banks seem to really like to now allow you to paste direct deposit information, which is insane. I get that they likely are thinking, well we don't want you type it into the first field and copy it into the second.

But I am copying it right from my bank's website, being forced to type it twice is just going to make it more likely I enter an error and I can guarantee you I am looking at that first field when I am typing the verification one.
