Your Authentication Code is automatically emailed to you when an account administrator grants you access to an Event. By default, this email comes from email@example.com, but your account may be configured to send from a custom address.
If you can't find your email, please contact your organization's account administrator. They are able to retrieve your Authentication Code manually or contact Lead Liaison support.
If you have administrator privileges in the back end web app, you can follow the instructions here to retrieve Authentication Codes: https://leadliaison.atlassian.net/wiki/spaces/LL/pages/18931801/GoExhibit#GoExhibit-RetrievingAuthenticationCodes
