If you register with other Federal online application systems, can you sign on to USAJOBS using the same logon and password from other Federal application systems?

Answer:

No. HHS Careers is linked directly with USAJOBS so your USAJOBS logon gives you access to apply to vacancies only in the HHS Careers system. It is true that some agencies use USAJOBS as a vehicle to post vacancies, but they link to separate application systems once you click to apply online.  You must create separate logons and passwords for those agencies' vacancies.
