# Standalone Spigot/Paper

Use this guide only when players connect directly to this server. Behind a proxy, use the [Velocity](/flp-wiki/install-and-deploy/velocity.md) or [BungeeCord](/flp-wiki/install-and-deploy/bungeecord.md) guide instead.

## Before installing

* Check [Java and dependency requirements](/flp-wiki/understand-flp/requirements.md).
* Choose one [supported auth plugin](/flp-wiki/compatibility-and-integrations/auth-plugins.md). AuthMe has a [dedicated integration guide](/flp-wiki/compatibility-and-integrations/authme.md).
* Obtain a ProtocolLib build compatible with the exact Minecraft/server version. ProtocolSupport is an alternative legacy integration; do not assume it covers every modern release.
* Back up the world, player data, auth database and any existing FLP data. Decide whether players should keep their existing UUIDs before first login.

## Install

### Install the plugins

Stop the server and put these plugins in `plugins/`:

| Plugin                | Choose                                                      |
| --------------------- | ----------------------------------------------------------- |
| FastLoginPlus         | The **Bukkit** edition, not `-plain.jar`                    |
| Authentication plugin | A version compatible with your server, such as AuthMe       |
| ProtocolLib           | A version compatible with your Minecraft and server version |
| {% endstep %}         |                                                             |

{% step %}

### Configure the server

Set `online-mode=false` in `server.properties`. This allows different login methods, but unverified players must still authenticate through the authentication plugin.

Once you have confirmed that players connect directly to this server, set `settings.bungeecord: false` in `spigot.yml`. On Paper, disable Velocity forwarding in Paper's configuration as well.
{% endstep %}

{% step %}

### Configure FLP

1. Start the server once, check that the plugins load, then stop it.
2. Open the generated `plugins/fastloginplus/config.yml`. Use the folder name actually generated on your server.
3. Review `premiumUuid`. The default is `true`; an existing offline server may need `false` to preserve its connection UUIDs. Read [UUIDs and player data](/flp-wiki/login-and-account-management/uuid.md) before changing it.
4. Adjust `autoRegister`, `autoLogin`, `auto-register-unknown` and `offline-whitelist` if needed. See [Bukkit and Folia configuration](/flp-wiki/configuration-reference/bukkit.md) for their purposes.
5. Set `language` to `en` or `zh`, then restart the server.
   {% endstep %}
   {% endstepper %}

## Verify

Check the startup log for plugin loading errors, then use test accounts to check premium login and an existing password account. An existing password account still requires its password until its owner agrees to bind it. For login dialog problems, see [troubleshooting](/flp-wiki/operations-and-troubleshooting/troubleshooting.md).

Before admitting public players, keep a password recovery method and an operator account available.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hayston.gitbook.io/flp-wiki/install-and-deploy/standalone.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
