The National Institutes of Health IT supports Google log in for use of NIH resources, including NLM's DOCLINE, via their iTrust user authentication portal.
We recommend that DOCLINE participants who are unable to create a Google account (even without Gmail) work with local IT support to get an exemption for Google authentication for use with DOCLINE. If you need further information or assistance with this process, please contact us.
Some libraries may be able to use the Research Organization login method if their facility is an officially registered NIH research partner. As a final option, login.gov is available but it not fully supported at this time.
