Please remove the multifactor authentication code from subject line of multifactor authentication emails

The multifactor authentication code sent to email is very useful, as everyone will agree. Email subject lines, though, are not a good place to display the code, IMHO. People can glance at desktop email notifications, inbox lists that display subject lines, and smartphone notifications too easily. I suggest only putting the code in the body of the email so users can choose exactly when the code is visible on their screen(s).
