The National Library of Medicine changed how people log into National Center for Biotechnology Information (NCBI) accounts. If you use an NCBI account to track PubMed searches, SciENcv, or MyNCBI, you will need to begin using federated account credentials authenticated by a third party to login. This will increase the security of your NCBI interactions. Third-party logins that can be used include Login.gov, USF's NetID, eRA Commons, NIH, ORCID, or your Google, Microsoft, or Facebook account.
Just your login changed. Your NCBI account remained the same with the same content. The only thing that changed is the way that you sign into it.
