With an ORCiD you can more easily showcase your accomplishments. Gather together all your research outputs from articles to posters in one researcher profile. ORCiD allows you to connect all your professional and scholarly accomplishments to feature them to potential collaborators, departments, employers, and funders.
ORCID lasts longer than your email address. If you change institutions you may lose touch with colleagues or potential collaborators will be get a failed email. If you chose to share your email, former colleagues and future collaborators will be able to find your most recent email address.
Not sure you want to share some information? That's okay! You can control what ORCID information is publicly shared.
