# Security Engines

### Block Commands Before Login (recommended)

```yaml
# What security engine to use. Possible values are listed and explained in the documentation.
type: 1
```

This mode is most suitable for all servers since it makes the player have the group before login so the other players can see the prefix the player has.

{% hint style="info" %}
This mode blocks commands before login.
{% endhint %}

### Add group after login <mark style="color:yellow;">(new)</mark>

```yaml
# What security engine to use. Possible values are listed and explained in the documentation.
type: 2
```

This mode adds the permissions after login. If the prefix is defined in the group, it will not show up. However, it is recommended to use type 1 instead since this is made mostly to support some types of server configurations.

{% hint style="warning" %}
A permission plugin like LuckPerms is required for this mode.
{% endhint %}
