Use your Cornell credentials to log into orcid.org. On the ORCID sign-in page, select "Institutional Account." You don't have to remember your ORCID iD!
Make your works public. This maximizes the potential for integration of your ORCID iD into other systems, and automatic updating of databases to attach your ORCID iD to your works.
Add at least some personal information (brief bio, education and/or employment) to your ORCID record, and make it public. This can help others distinguish you from people with the same name, if they don't know your ORCID iD.
Add name variants, if you have published under other names or variations of your name.
Use your ORCID iD when prompted in processes such as manuscript submission and grant proposals and reporting (e.g. eRA Commons).
Include your ORCID on conference posters (generate a QR code, if you like, right from your ORCID record page), to direct people to your works.
Consider including your ORCID iD on your webpage, in social media accounts, and in your email signature.
For display, ORCID recommends using the entire URL and ORCID iD logo:
