Reddit

Get your Reddit Credentials

To use Reddit sign in, you need a client ID and client secret. You can get them from the Reddit Developer Portal.

1. Click "Create App" or "Create Another App"
2. Select "web app" as the application type
3. Set the redirect URL to http://localhost:3000/api/auth/callback/reddit for local development
4. For production, set it to your application's domain (e.g. https://example.com/api/auth/callback/reddit)
5. After creating the app, you'll get the client ID (under the app name) and client secret

If you change the base path of the auth routes, make sure to update the redirect URL accordingly.

Configure the provider

To configure the provider, you need to import the provider and pass it to the socialProviders option of the auth instance.

import { betterAuth } from "better-auth"
 
export const auth = betterAuth({
    socialProviders: {
        reddit: {
            clientId: process.env.REDDIT_CLIENT_ID as string,
            clientSecret: process.env.REDDIT_CLIENT_SECRET as string,
        },
    },
})

Sign In with Reddit

To sign in with Reddit, you can use the signIn.social function provided by the client. The signIn function takes an object with the following properties:

• provider: The provider to use. It should be set to reddit.

import { createAuthClient } from "better-auth/client"
const authClient = createAuthClient()
 
const signIn = async () => {
    const data = await authClient.signIn.social({
        provider: "reddit"
    })
}
