DOCLINE Log In Steps

DOCLINE users need two accounts to sign in:  A DOCLINE user account, and an external account for identity verification. Most DOCLINE users authenticate (verify their identity) by logging in with Google accounts. Other users, including those at federal libraries or NIH-affiliated Research Organizations, have alternate methods available for signing into DOCLINE.

First time users:
  • Make sure the email used in your external account (Google or Gmail,, federal SmartCard, or Research Organization network) matches your DOCLINE username.
  • Verify that you can use your external account to directly log in to Google, or your network to make sure the account works successfully outside DOCLINE.
