code sent for email

Um...my husband is having the same problem.  The issue with your answer is that there's a little box to check underneath the passcode box that says "don't ask me again on this platform".  He checks it -edited- he logs in he is required to get a passcode -edited- , despite having checked the -edited- box!!! It never happens on email login on his phone. And it never happens to me on email login on my iPad, iPhone, or laptop. What gives? How to fix this?
