If you do not already have an ORCID ID, you can claim one at https://orcid.org/register
Use your UNM email when you register, and set your privacy preferences using the options listed. Note that "public" is the default option for your profile, while "limited" allows you to exchange information with select organizations.
If you already have an ORCID ID, you don't need another one as this ID will be yours uniquely throughout your career as a researcher. However, you may want to connect your ID to UNM systems. Once connected, you can log in to your ORCID account using your UNM network credentials. You can also push citations/achievements from your ORCID profile to UNM activity reporting or grant application systems, saving yourself time in the long run.
To connect your ID, navigate to https://orcid.org/signin and click on the button to "Access through your institution." Once you select UNM as your home institution and sign in with your ORCID credentials, your ORCID will be linked to UNM.
