If you would like to add a connected account and you did not already create your account with it you can do so from your account settings.
Simply click on the account provider you would like to connect (ORCID, Google, or LinkedIn) and a dialogue will open taking you through the process of adding that account. Note no more than one account from each of these providers can be associated with a Publons account.
Once associated with your Publons account, you can use these as log in methods for the site. Connecting an ORCID account also allows you to import publications from your ORCID record.
You can disassociate any connected accounts from this same page by clicking on the trash icon alongside the account you wish to remove.
