# Running a Safety Scan

Installing Safety and running your first security scan is easy.

### 📝 Run your first security scan

Running your first scan in the command line only takes a few seconds.

Open up your command line / terminal interface and navigate to the Python repository or codebase you want to run a security scan on.

Download our Safety CLI from PyPi:

```
// pip install safety
```

Run the security scan using Safety. You can find your API key on your account dashboard when you create an account or log into Safety.

```
// safety check --key <your_api_key>
```

In this example, Safety is scanning your local Python environment for every package or dependency that is installed and checking it against our industry-leading Python Dependency Vulnerability database.
