Why does the error message say "Wrong email or password?

Why can't you tell me if the email address is wrong?

We don't provide that information for security reasons. We don't want bots or hackers figuring out who has a valid email address because the next step is to figure out a password. If the hacker doesn't know either then our system is less vulnerable.

We do tell you what email address the password reset was sent to as a check for you.  If an error is not corrected, then you will never receive the reset email. 

Yes, I know its a bit frustrating but it is done for the best reason - to keep the system secure.
