Google

Get your Google credentials

To use Google as a social provider, you need to get your Google credentials. You can get them by creating a new project in the Google Cloud Console.

Make sure to set the redirect URL to http://localhost:3000/api/auth/callback/google for local development. For production, you should set it to the URL of your application. If you change the base path of the auth routes, you should update the redirect URL accordingly.

Configure the provider

To configure the provider, you need to pass the clientId and clientSecret to socialProviders.google in your auth configuration.

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

Signin with Google

To signin with Google, 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 google.

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