Auth

Login with Bitbucket

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

Overview

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

Access your Bitbucket account

  • Go to bitbucket.org.
  • Click on Login at the top right to log in.

Bitbucket 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 Bitbucket 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 Bitbucket OAuth app

  • Click on your profile icon at the bottom left
  • Click on All Workspaces
  • Select a workspace and click on it to select it
  • Click on Settings on the left
  • Click on OAuth consumers on the left under Apps and Features (near the bottom)
  • Click Add Consumer at the top
  • Enter the name of your app under Name
  • In Callback URL, type the callback URL of your app
  • Check the permissions you need (Email, Read should be enough)
  • Click Save at the bottom
  • Click on your app name (the name of your new OAuth Consumer)
  • Copy your Key (client_key) and Secret (client_secret) codes

Add your Bitbucket 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 Bitbucket from the accordion list to expand and turn Bitbucket Enabled to ON
  • Enter your Bitbucket Client ID and Bitbucket Client Secret saved in the previous step
  • Click Save

Add login code to your client app

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


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