❤️ Become a Sponsor of my Open Source Work

⭐ This repository if you found it useful!

Summary

If you ever wanted to go with a passwordless login or authentication method. This is allows you to utilize Discord to help with user logins by utilize the oAuth2 Service provided by Discord.

This was meant to be as intuitive as possible but also as secure as we can make it. Which means we utilize an express server to help mitigate fake client-side data.

This resource requires opening port 7790.

This resource requires a Discord Developer Application. (Free)

If you plan on using the whitelist it requires a Discord Bot. (Free)

This also comes with an optional whitelist where you can give players a role in order to get into the server. The whitelist automatically updates when you add or remove a role from the user. It also automatically re-parses the whitelist every 60 seconds.

Looking for a traditional login with Username and Password? Try out alt:V OS Auth.

Prerequisites

I cannot stress this enough. Ensure you have NodeJS 13+ or you will have problems.

NodeJS 13+
An Existing or New Gamemode
General Scripting Knowledge

After simply add the name of this resource to your server.cfg resource section. It must be named exactly like this.

altv-discord-auth

Then simply clone this repository into your main server resources folder.

cd resources
git clone https://github.com/Stuyk/altv-discord-auth

After cloning, navigate to resources/altv-discord-auth directory and simply run npm install to install needed dependencies.

Port Forward

Open Port 7790 for your express server.

Generating Your Bot

Create a Discord Bot at https://discord.com/developers/

Click here to see a .gif of the process.

Add oAuth2 Redirect

You will need to add a specific file path to the oAuth2 bot. This setting can be found in the oAuth2 category of the discord developers application.

Append the Following for Redirects

http://127.0.0.1:7790/authenticate

http://<your_server_ip>:7790/authenticate

Make sure to save!

Inviting Your Bot

You simply visit the oAuth2 section of the discord developers application. Tick bot in scopes. Then tick administrator in bot permissions (optional just make sure your bot can see all users). After you copy the link and paste it in your browser.

Updating Environment Variables

MAKE SURE TO READ ALL OF THIS. IT'S VERY IMPORTANT.

Open your .env file which should be located in the same directory as your altv-server file. Running this resource without the .env will generate it automatically. If you are not sure what a .env file is please use google.

Showing the Authentication Window

When a player first joins your server you will want to emit this event. We do not do it for you.

Server-Side

alt.on('playerConnect', playerConnect);

function playerConnect(player) {
    alt.emit('discord:BeginAuth', player);
}

After Authentication

The users general Discord Information will be sent to you through an alt event. You will also recieve the player which it belongs to. The window will automatically close for that user.

Server-Side

alt.on('discord:AuthDone', playerAuthDone);

function playerAuthDone(player, discordInfo) {
    console.log(discordInfo);
}
