Connect an Existing ORCID ID to WSU
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 WSU systems. Once connected, you can log in to your ORCID account using your WSU network credentials. You can also push citations/achievements from your ORCID profile to WSU 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 "Institutional account" tab. Once you select WSU as your home institution and sign in with your ORCID credentials, your ORCID will be linked to WSU.
