Using Touch ID on Macbook Pro for sudo Authentication and iTerm

Posted on

Full credit goes to Cabel Sasser on this one for sharing the original tip.

  1. In iTerm type:

    $ sudo vim /etc/pam.d/sudo

  2. Enter your credentials

  3. 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.so
session    required       pam_permit.so

  4. The sudo file is readonly. To save and exit type:

    :wq!

  5. (Optional since we're focusing on iTerm) To Reload your shell:

    $ $SHELL

  6. Go to Prefs -> Advanced -> Allow sessions to survive logging out and back in and set value to No.

  7. Restart iTerm

  8. Type any command with sudo to make sure it works:

    $ sudo echo
