I don't find where to use ORCID to login and hope you help me.

Online usage 

The tutorial server is hosted by the Center for Computation & Technology at LSU. 

Our system uses CILogin To login, go to the web server, https://etk.cct.lsu.edu/, and click on the "Sign in with CILogon" button. You will then be redirected to your university and sign on with your university login. If your university is not a member of CILogin, then please obtain a free ORCID account and use that one with CILogin (note that for ORCID to work you must set your email visibility to "Everyone." That's a green eye icon next to your address in settings.).
