Just as you have an identity number for the government or for work, having a unique, personal identifier for your publications is very important.

ORCID allows the world to know that this publication is yours and not any of the other David/Yael Cohens. Today many journals and grants insist that you have an ORCID. It takes a few minutes to register at https://orcid.org/register. If you need any assistance contact your librarian at library@weizmann.ac.il.
