Fort Knox level account protection here

The last thing you want to do is verify if you know the email by resetting your password. You'll never get that password email, and thus lose your temp password.

To make sure you have the birthday correct, you need the birthday to change your password anyway. Go to your account page and verify there. I'm not sure how you can check your email for your own account, to tell you the truth.

You can request a PIN reset via email. If I remember correctly, it doesn't go into effect unless you receive the email and click the link.

Or what Steve suggested.
