You can export and review the metadata that npm stores about your personal account. The export is an archive containing the following information.
After a request is placed our support team will review it and initiate an export on your behalf. Once the export process is complete you will receive an email with a link to an archive of your personal data. You must be authenticated to npmjs.com to download this archive.
The download link will be available for 7 days, after which the exported data and the link is purged.
