My NCBI and the Primary Data Archive (PDA) Account Login
National Center for Biotechnology Information (NCBI) Primary Data Archive (PDA) accounts are used for sequence and genomic data submissions. NCBI will be consolidating the PDA login system with the My NCBI login system.
PDA account users will access their account through the My NCBI sign in page using their current username and password. Users who have PDA and My NCBI accounts with the same username will be prompted to merge the two accounts to have one set of login credentials (username and password) to be used with the My NCBI sign in page.
In the future, the My NCBI sign in page will be the single sign on authentication system for all NCBI accounts.
