# Install
This article will show you how to install the Qwiet CLI and how to associate it with your Qwiet account.
### Step 1: Download and install the Qwiet CLI
{% tabs %}
{% tab title="Linux/macOS" %}
Run the following shell command:
```
curl https://cdn.shiftleft.io/download/sl >/usr/local/bin/sl && chmod a+rx /usr/local/bin/sl
```
 
{% endtab %}
{% tab title="Windows" %}
Run the following Powershell command to begin your download:
```
Invoke-WebRequest -Uri 'https://cdn.shiftleft.io/download/sl-latest-windows-x64.zip' -OutFile sl-latest-windows-x64.zip
```
 
Extract the contents of the archive:
```
Expand-Archive -Path sl-latest-windows-x64.zip -DestinationPath .
```
 
Add the Qwiet CLI to your system `PATH`.
{% endtab %}
{% endtabs %}
### Step 2: Authenticate with Qwiet
Once you have the Qwiet CLI installed, you need to associate the CLI with your Qwiet account.
First, you'll need your access token, which you can obtain in the [Dashboard](https://app.shiftleft.io/user/profile).
Once you have your access token, create an environment variable called `SHIFTLEFT_ACCESS_TOKEN` and set its value to your access token.
### Using `sl auth` to authenticate
While setting an environment variable called `SHIFTLEFT_ACCESS_TOKEN` and using that to authenticate is the preferred method, you can also run `sl auth` to link the CLI with your Qwiet account.
{% tabs %}
{% tab title="Linux/macOS" %}
```
sl auth --token "YOUR_ACCESS_TOKEN"
```
 
{% endtab %}
{% tab title="Windows" %}
```
sl.exe auth --token "YOUR_ACCESS_TOKEN"
```
 
{% endtab %}
{% endtabs %}
