  4. Test your login process, in this case via ssh to the RC login nodes:
  5. Use your CU IdentiKey username ssh @login.rc.colorado.edu or ssh -l login.rc.colorado.edu and note that "ssh -l" uses a lowercase L.
  6. Enter duo: followed by your IdentiKey Password at the password prompt, i.e. if your password is MyUCB_PW you enter duo:MyUCB_PW as your password.
