You can access SciENcv a number of ways. The easiest is by going to https://www.ncbi.nlm.nih.gov/sciencv/ and selecting your preferred log-in method.
My NCBI is a tool designed for multiple purposes across the NCBI system, including saving and customizing NCBI database searches and creating bibliographies of your own work, in addition to housing the SciENcv system. If you’re not familiar with My NCBI, finding SciENcv once you’re in My NCBI can be a bit tricky. For most users, the SciENcv box will default to the bottom right corner of your screen, but if you have customized your My NCBI account before, it may be located elsewhere.
NIH eRA Commons, NSF (Research.gov), and ORCID account holders who have linked their accounts to NCBI can populate their SciENcv profiles with the information stored in their eRA, FastLane, or ORCID accounts.
