Full credit goes to Cabel Sasser on this one for sharing the original tip. In iTerm type: $ sudo vim /etc/pam.d/sudo Enter your credentials Add the following line after the first line: auth sufficient pam_tid.so Your file should now look something like this: # sudo: auth account password session auth sufficient pam_tid.so auth sufficient pam_smartcard.so auth required pam_opendirectory.so account required pam_permit.so password required pam_deny.
