You can quickly and easily remove your duplicate record by going to your Account Settings and selecting Remove duplicate record. You will then be prompted to enter in the email address or ORCID iD of the duplicate record, as well as the password.
When the duplicate record is removed, the email address attached to it will be added to your primary ORCID record, and all other information on the record will be deleted.
For more information, please see removing your additional or duplicate ORCID iD.
If you no longer have access to that email account and do not recall the password, please contact us with your full name, your 16-digit ORCID identifier, and any email addresses you may have registered for an account with.
