# Configuration Options 📋
## One Wildcard Certificate for All Subdomains
By default, each subdomain gets its own certificate. You can **enable a wildcard certificate** by setting:
```yaml
enable_wildcard_certificate: true
```
## Pros & Cons of a Wildcard Certificate
### Pros
-**Improves performance** by reducing TLS handshakes.
-**Simplifies certificate management** (one cert for all subdomains).
### Cons
-**Requires manual DNS challenge setup** for Let's Encrypt.
-**Needs additional configuration for automation** (see below).
If enabled, update your inventory file and follow the **[manual wildcard certificate setup](SETUP.md)**.
