How to Install Geyser and Floodgate

Introduction

First some important notes regarding this.

With Geyser alone, a Bedrock player must have a valid, paid Java Edition account to authenticate and join.
With Geyser + Floodgate, Bedrock players can join without a Java account. This is required for console players (Xbox, PlayStation, Switch) and is ideal for easier access.

Versions

You can use Geyser-Spigot on servers that run on 1.16.5 or above. Do note that Geyser requires Java 17 to run!

chat signing

In order for Bedrock players to chat (1.19.3+) or join (1.19.1/1.19.2), you need to disable chat signing.

Vanilla, Spigot/Paper/forks, Fabric, NeoForge

Set enforce-secure-profile: false in server.properties

BungeeCord and forks

Set enforce_secure_profile: false in config.yml

Velocity

Set force-key-authentication = false in velocity.toml

Due to Bedrock automatically updating clients, Via Version is heavily recommended.
If this is not used. Bedrock users with a later version than the server won't be able to connect. Updating a plugin is also easier than the whole server.

Installing on a Server(Spigot/Paper)

Your server is already using an assigned port. We can use this. You need to find one additional port for Bedrock players.

If you do HAVE dedicated ports (25565, 19132) you can move to the next step. If you do NOT have dedicated ports, Find one free port in your allocation list for Bedrock players. If none are free, click Create Allocation to add a new port. Remember this port number. network-allocation

Navigate to the Templates tab on the left.

Select GeyserMC

Make sure Include Floodgate is selected. (it's enabled by default)

Select GeyserMC Type by default this is spigot and works on all forks.

Select the Bedrock Port you assigned earlier from the list.

Press Install and click Okay on the new window that appears.

Go to the files tab and to this file /plugins/Geyser-Spigot/config.yml and change your java port if it's not 25565. We selected the bedrock port before.

remote:
  # The IP address of the remote (Java Edition) server
  # If it is "auto", for standalone version the remote address will be set to 127.0.0.1,
  # for plugin versions, it is recommended to keep this as "auto" so Geyser will automatically configure address, port, and auth-type.
  # Leave as "auto" if floodgate is installed.
  address: auto
  # The port of the remote (Java Edition) server
  # For plugin versions, if address has been set to "auto", the port will also follow the server's listening port.
  port: 25575
