How do I reset my password?

If you have forgotten the password which corresponds to your LOINC username, go to loinc.org/forgot. The form will ask you to enter your username or email address. If located, it will email you a link to change your password.

When I log in to the LOINC.org website, how long will I remain logged in?

If you use your LOINC username and password to sign in to our website, you will stay logged in until:

  • You close/exit your web browser
  • Or, two days have passed from when you initially logged in
  • Or, if you tick the “Remember me” checkbox at login, two weeks have passed.

Note: LOINC.org’s website authentication requires the use of Cookies within your browser, i.e. Chrome, Firefox, or Safari. Changing the security/cookie storage settings within your browser may alter this behavior.

If you are using a public computer, we encourage you to log out and exit the web browser once you have completed your work.
