Weird login bug

So I entered my password a few times and tried to log in and nothing happened, it said the password wasnt correct, then I slowly re-entered it again and made sure everything was correct, it was correct but it still said the password was wrong, then I for some reason started spamming the log in button and after about 30 seconds of non stop spamming the button (No I wasnt changing the password I was just spamming the button) it for some reason let me in....
