Auth

Login with Twitter


To enable Twitter Auth for your project, you need to set up a Twitter OAuth application and add the application credentials in the Supabase Dashboard.

Overview

Setting up Twitter logins for your application consists of 3 parts:

Access your Twitter Developer account

Twitter Developer Portal.

Find your callback URL

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

  • Go to your Supabase Project Dashboard
  • Click on the Authentication icon in the left sidebar
  • Click on Providers under the Configuration section
  • Click on Twitter from the accordion list to expand and you'll find your Callback URL, you can click Copy to copy it to the clipboard

Create a Twitter OAuth app

  • Click + Create Project.
    • Enter your project name, click Next.
    • Select your use case, click Next.
    • Enter a description for your project, click Next.
    • Enter a name for your app, click Next.
    • Copy and save your API Key (this is your client_id).
    • Copy and save your API Secret Key (this is your client_secret).
    • Click on App settings to proceed to next steps.
  • At the bottom, you will find User authentication settings. Click on Set up.
  • Under User authentication settings, you can configure App permissions.
  • Make sure you turn ON Request email from users.
  • Select Web App... as the Type of App.
  • Under App info configure the following.
    • Enter your Callback URL. Check the Find your callback URL section above to learn how to obtain your callback URL.
    • Enter your Website URL (tip: try http://127.0.0.1:port or http://www.localhost:port during development)
    • Enter your Terms of service URL.
    • Enter your Privacy policy URL.
  • Click Save.

Enter your Twitter credentials into your Supabase project

  • Go to your Supabase Project Dashboard
  • In the left sidebar, click the Authentication icon (near the top)
  • Click on Providers under the Configuration section
  • Click on Twitter from the accordion list to expand and turn Twitter Enabled to ON
  • Enter your Twitter Client ID and Twitter Client Secret saved in the previous step
  • Click Save

Add login code to your client app

When your user signs in, call signInWithOAuth() with twitter as the provider:


_10
async function signInWithTwitter() {
_10
const { data, error } = await supabase.auth.signInWithOAuth({
_10
provider: 'twitter',
_10
})
_10
}

For a PKCE flow, for example in Server-Side Auth, you need an extra step to handle the code exchange. When calling signInWithOAuth, provide a redirectTo URL which points to a callback route. This redirect URL should be added to your redirect allow list.

In the browser, signInWithOAuth automatically redirects to the OAuth provider's authentication endpoint, which then redirects to your endpoint.


_10
await supabase.auth.signInWithOAuth({
_10
provider,
_10
options: {
_10
redirectTo: `http://example.com/auth/callback`,
_10
},
_10
})

At the callback endpoint, handle the code exchange to save the user session.

Create a new file at app/auth/callback/route.ts and populate with the following:

app/auth/callback/route.ts

_38
import { cookies } from 'next/headers'
_38
import { NextResponse } from 'next/server'
_38
import { type CookieOptions, createServerClient } from '@supabase/ssr'
_38
_38
export async function GET(request: Request) {
_38
const { searchParams, origin } = new URL(request.url)
_38
const code = searchParams.get('code')
_38
// if "next" is in param, use it as the redirect URL
_38
const next = searchParams.get('next') ?? '/'
_38
_38
if (code) {
_38
const cookieStore = cookies()
_38
const supabase = createServerClient(
_38
process.env.NEXT_PUBLIC_SUPABASE_URL!,
_38
process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!,
_38
{
_38
cookies: {
_38
get(name: string) {
_38
return cookieStore.get(name)?.value
_38
},
_38
set(name: string, value: string, options: CookieOptions) {
_38
cookieStore.set({ name, value, ...options })
_38
},
_38
remove(name: string, options: CookieOptions) {
_38
cookieStore.delete({ name, ...options })
_38
},
_38
},
_38
}
_38
)
_38
const { error } = await supabase.auth.exchangeCodeForSession(code)
_38
if (!error) {
_38
return NextResponse.redirect(`${origin}${next}`)
_38
}
_38
}
_38
_38
// return the user to an error page with instructions
_38
return NextResponse.redirect(`${origin}/auth/auth-code-error`)
_38
}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:


_10
async function signOut() {
_10
const { error } = await supabase.auth.signOut()
_10
}
