If you set up an “Account Recovery Email”, you can use the automated system to reset your password in the future.

To add/update your account security email address.  Login and click “User Menu” at the top right where the red arrow is pointing.  Then click “Settings” in the yellow circle.  After that, go to “Account Settings”.  Once you’re there, you will see an option to add a new account security email or update an existing one.
