Previously known as Publons, Web of Science Researcher profiles allows you both to control which publications appear in your Web of Science record, and to track your citation metrics, peer reviews, and journal editing work. To sign up for a profile, go to webofscience.com and register.
If you already had a Publons account set up, you can log in with the same credentials.
