# TouchID for Sudo

## Overview

Instead of having to type our password each time we use `sudo` we can instead use Touch ID on our mac keyboards. 

{% hint style="warning" %}
While we can use the `/etc/pam.d/sudo` file for this, changes will not survive system updates, and if we accidentally mess something up, it's [quite a pain](https://medium.com/@zmre/quick-tip-fixing-the-sudo-file-on-macos-cf3c2a2584d4) to fix it!
{% endhint %}

Instead, we can 

* Copy the file `/etc/pam.d/sudo_local.template` to `/etc/pam.d/sudo_local` 
* Then remove the `#` in front of the `auth` like below

```bash
# /etc/pam.d/sudo_local
𝗮𝘂𝘁𝗵    𝘀𝘂𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁   𝗽𝗮𝗺_𝘁𝗶𝗱.𝘀𝗼
```

Then save, and the next time you run sudo, you'll be prompted for Touch ID instead of your password.
