Coding Frontend: HTML, CSS, JS

BOGUS! How do you expect someone to go verify their 4-digit code that YOU JUST SENT... two separate times, when the screen resets itself every time I have to leave the app, go retrieve my email and then come back to give the code only to have it say UNAUTHORIZED?! I mean, it doesn't take a rocket scientist a fairy godmother and a handful of miraculous events, here. THINK, McFly, THINK!
