Having the ability to use Touch ID for sudo is handy. I’ve been using it for a while.

Coupled with `expect` I use it to authenticate through SSH (that is the only feasible option I got to connect to hosts I’ve got limited access). I even wrote about it: https://antonio-ramadas.github.io/blog/2020/10/30/ssh-login-...

Here is the gist of it:

  #!/usr/bin/expect
  
  # Connects via SSH to the host passed as argument
  
  set timeout 60
  set server [lindex $argv 0]
  set username <USERNAME>
  set password [exec sudo cat <PATH_TO_YOUR_PASSWORD_FILE>]
  
  spawn ssh $username@$server
  
  expect { 
   "yes/no" { send "yes\r" ; exp_continue }
   "\*?assword" { send "$password\r" }
  }
  
  interact

Edit: Please remove all permissions from the password file with:

  chmod a-rwx <PATH_TO_PASSWORD_FILE>

I’m also assuming you run this script on an environment you control and trust. Be wary of your password.
