If you forgot your password and need to reset your password there is a "RESET PASSWORD" link just below the Login button on the login page: https://pheedloop.com/keystoneofrecovery/virtual/.  Enter the email address you used to register for the conference and a new password reset email will be immediately sent to your email address.

If you want to set your own unique password, use the "Account" tab under the live event portal after logging in to set a new password as shown below.
