The first time you sign in using your institutional or social media account from ORCID, you will be asked to connect your ORCID account by signing in using your ORCID username (email address or ORCID iD) and password, and then confirm that the accounts be linked. After that, you may sign in using your ORCID credentials or any linked account.
You may link multiple institutional or other accounts to your ORCID account. Once linked, any of these may be used to access your ORCID record. To link multiple accounts, repeat the linking procedure for each additional account.
You can view the accounts that you have linked to your ORCID record in your account settings.
