## Before you start

You'll need console access to your server. This plugin supports Paper 1.20.x through 1.21.x.

> Back up your server before installing any authentication plugin.

## Install the plugin

1. Stop your server.
2. Drop `ZCraftAuth.jar` into `/plugins`.
3. Start it once to generate the default config.

```yaml
session-timeout: "30m"
require-login: true
```

## Confirm it works

Join with an alt account — you should be prompted with `/login <password>`.
