If you have MacBook Pro with Touch Bar, you can improve your experience of the command line. You can enable Touch ID to authenticate sudo.
Open the file /etc/pam.d/sudo:
sudo vi /etc/pam.d/sudo
Then add the following line.
auth sufficient pam_tid.so
Your /etc/pam.d/sudo should now like this:
# sudo: auth account password session auth sufficient pam_smartcard.so auth sufficient pam_tid.so auth required pam_opendirectory.so account required pam_permit.so password required pam_deny.so session required pam_permit.so
If you use sudo now, you will be asked for your fingerprint.
