Are you stuck trying to login with OAuth Discord provider from a non-host device using Auth.js? Well, you’re not alone! Many developers face this issue, and it’s frustrating, to say the least. But don’t worry, we’ve got you covered. In this article, we’ll dive into the problem, explore the reasons behind it, and provide a step-by-step guide to fix it once and for all.
The Problem: Cannot Login with OAuth Discord Provider
When trying to login with OAuth Discord provider from a non-host device using Auth.js, you might encounter an error message like this:
Cannot login with OAuth Discord provider from non-host device.
This error message can be misleading, and it’s easy to get lost in the sea of documentation and troubleshooting articles. But fear not, dear developer! We’ll break it down for you in simple terms.
What is OAuth?
OAuth (Open Authorization) is an authorization protocol that allows users to grant third-party applications limited access to their resources on another service provider’s website, without sharing their login credentials. In our case, we’re using OAuth to authenticate with Discord.
What is Auth.js?
Auth.js is a popular JavaScript library for authentication and authorization. It provides a simple, modular, and flexible way to handle authentication in your applications. Auth.js supports various providers, including Discord OAuth.
The Reasons Behind the Issue
So, why can’t you login with OAuth Discord provider from a non-host device? There are a few reasons:
- Security Restrictions: Discord has security restrictions in place to prevent abuse and unauthorized access. One of these restrictions is that OAuth authentications can only be initiated from the registered redirect URI or a localhost.
- Host Device vs. Non-Host Device: When you register an OAuth application with Discord, you specify a redirect URI. This redirect URI is tied to a specific host device. If you try to login from a non-host device, Discord won’t recognize the request and will throw an error.
- Auth.js Configuration: Auth.js requires proper configuration to work correctly with Discord OAuth. If your configuration is incorrect, you might encounter issues.
The Solution: Fixing the Issue
Now that we’ve identified the problem and the reasons behind it, let’s dive into the solution!
Step 1: Register a New OAuth Application with Discord
First, you need to register a new OAuth application with Discord. Follow these steps:
- Go to the Discord Developer Portal and click on “Create an Application.”
- Fill in the required information, such as the application name, description, and redirect URI.
- Note down the client ID and client secret, as you’ll need them later.
Step 2: Configure Auth.js with Discord OAuth
Next, you need to configure Auth.js to work with Discord OAuth. Add the following code to your Auth.js configuration:
import { Auth } from '@auth/core';
import { DiscordAuthProvider } from '@auth/discord';
const auth = new Auth({
providers: [
new DiscordAuthProvider({
clientId: 'YOUR_CLIENT_ID',
clientSecret: 'YOUR_CLIENT_SECRET',
authorizationUrl: 'https://discord.com/api/oauth2/authorize',
tokenUrl: 'https://discord.com/api/oauth2/token',
redirectUri: 'http://localhost:3000/callback',
}),
],
});
Step 3: Add the Redirect URI to the Discord OAuth Application
Go back to the Discord Developer Portal and add the redirect URI to your OAuth application:
In the “OAuth2” section, click on “Add Redirect” and enter the redirect URI you specified in the Auth.js configuration (e.g., http://localhost:3000/callback
). Click “Save Changes.”
Step 4: Handle the Callback
When the user is redirected back to your application after authorization, you need to handle the callback:
app.get('/callback', async (req, res) => {
try {
const { token } = await auth.getAccessToken(req.url);
const user = await auth.getUser(token);
// Login successful, redirect to protected route
res.redirect('/protected');
} catch (error) {
console.error(error);
// Handle errors
}
});
Step 5: Test the Login Flow
Finally, test the login flow by visiting your application’s login page and clicking on the “Login with Discord” button. If everything is configured correctly, you should be redirected to the Discord authorization page, and then back to your application after authorization.
Troubleshooting Common Issues
If you encounter issues during the login flow, check the following:
- Incorrect Client ID or Client Secret: Double-check that you’ve entered the correct client ID and client secret in your Auth.js configuration.
- Invalid Redirect URI: Ensure that the redirect URI in your Auth.js configuration matches the one registered in the Discord Developer Portal.
- Insecure HTTP Connection: Make sure your redirect URI uses HTTPS (SSL/TLS) or localhost (
http://localhost:3000/callback
). Discord OAuth requires a secure connection. - Auth.js Configuration Errors: Review your Auth.js configuration for any syntax errors or typos. Consult the Auth.js documentation for reference.
Conclusion
In this article, we’ve covered the common issue of not being able to login with OAuth Discord provider from a non-host device using Auth.js. We’ve explored the reasons behind the issue and provided a step-by-step guide to fix it. By following these instructions, you should be able to successfully implement Discord OAuth authentication in your application.
Remember to test your implementation thoroughly and troubleshoot any issues that arise. If you’re still stuck, feel free to ask for help in the comments or seek assistance from the Auth.js community.

Frequently Asked Question
Get the answers to your burning questions about OAuth Discord provider login issues from non-host devices using Auth.js!
Why can’t I login with OAuth Discord provider from a non-host device using Auth.js?
This is likely due to the OAuth redirect URI not being configured correctly. Make sure the redirect URI in your Discord OAuth settings matches the one in your Auth.js configuration. Double-check for any typos or mismatched URLs!
Is there a specific Auth.js configuration that I need to use for OAuth Discord login?
Yes, you’ll need to configure the OAuth Discord provider in your Auth.js settings. This includes setting the `clientId`, `clientSecret`, and ` authorizationUrl` fields. You can find more information in the Auth.js documentation or by searching for Discord OAuth tutorials.
Can I use the same OAuth Discord credentials for both host and non-host devices?
No, you’ll need to create separate OAuth credentials for each device type. Discord OAuth requires different credentials for host and non-host devices. This is a security measure to prevent unauthorized access to your application.
Why do I get a “redirect_uri_mismatch” error when trying to login with OAuth Discord?
This error usually occurs when the redirect URI in your Discord OAuth settings doesn’t match the one in your Auth.js configuration. Double-check that the URLs match exactly, including any trailing slashes or-www/non-www domains.
How do I troubleshoot OAuth Discord login issues with Auth.js?
Start by checking the Auth.js documentation and Discord OAuth tutorials for any configuration issues. Then, review your OAuth credentials and redirect URIs for any typos or mismatches. Finally, check your browser console for any error messages or debug logs that can help you identify the issue.
