To enable Google Auth for your project, you need to set up a Google OAuth application and add the application credentials to your Supabase Dashboard.
|
|
|
|
## Overview
|
|
|
|
Setting up Google logins for your application consists of 3 parts:
|
|
|
|
- Create and configure a Google Project on the [Google Cloud Platform Console](https://console.cloud.google.com/home/dashboard)
|
|
- Add your Google OAuth keys to your [Supabase Project](https://app.supabase.com)
|
|
- Add the login code to your [Supabase JS Client App](https://github.com/supabase/supabase-js)
|
|
|
|
## Steps
|
|
|
|
### Access your Google Cloud Platform account
|
|
|
|
- Go to [cloud.google.com](https://cloud.google.com).
|
|
- Click on `Sign in` at the top right to log in.
|
|
|
|
|
|
|
|
### Create a Google Cloud Platform Project
|
|
|
|
- Click on `Select a Project` at the top left.
|
|
- (Or, if a project is currently selected, click on the current project name at the top left.)
|
|
- Click `New Project` at the top right.
|
|
- Fill in your app information, then click `Create`.
|
|
- (This can take a few minutes.)
|
|
- This should bring you to the dashboard for your new project.
|
|
|
|
### Create the OAuth Keys for your project
|
|
|
|
From your project's dashboard screen:
|
|
|
|
- In the search bar at the top labeled `Search products and resources` type `OAuth`.
|
|
- Click on `OAuth consent screen` from the list of results.
|
|
- On the `OAuth consent screen` page select `External`.
|
|
- Click `Create`.
|
|
|
|
### Edit your app information
|
|
|
|
- On the `Edit app registration` page fill out your app information.
|
|
- Click `Save and continue` at the bottom.
|
|
|
|
### 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](https://app.supabase.com).
|
|
- Click on the `Settings` icon at the bottom of the left sidebar.
|
|
- Click on `API` in the list.
|
|
- Under Config / URL you'll find your API URL, you can click `Copy` to copy it to the clipboard.
|
|
- Now just add `/auth/v1/callback` to the end of that to get your full `OAuth Redirect URI`.

|
### Create your credentials
|
|
|
|
- Click `Credentials` at the left to go to the `Credentials` page
|
|
- Click `Create Credentials` near the top then select `OAuth client ID`
|
|
- On the `Create OAuth client ID` page, select your application type. If you're not sure, choose `Web application`.
|
|
- Fill in your app name.
|
|
- At the bottom, under `Authorized redirect URIs` click `Add URI`.
|
|
- Enter your callback URI under `Authorized redirect URIs` at the bottom.
|
|
- Enter your callback URI in the `Valid OAuth Redirect URIs` box.
|
|
- Click `Save Changes` at the bottom right.
|
|
- Click `Create`.
|
|
|
|
Copy your new OAuth credentials
|
|
|
|
- A box will appear called `OAuth client created`.
|
|
- Copy and save the values under `Your Client ID` and `Your Client Secret`.
|
|
|
|
### Enter your Google credentials into your Supabase Project
|
|
|
|
- Go to your [Supabase Project Dashboard](https://app.supabase.com)
|
|
- In the left sidebar, click the `Authentication` icon (near the top)
|
|
- Click `Settings` from the list to go to the `Authentication Settings` page
|
|
- Enter the final (hosted) URL of your app under `Site URL` (this is important)
|
|
- Under `External OAuth Providers` turn `Google Enabled` to ON
|
|
- Enter your `Google Client ID` and `Google Client Secret` saved in the previous step
|
|
- Click `Save`
|
|
|
|
### Add login code to your client app
|
|
|
|
The JavaScript client code is documented here: [Supabase OAuth Client Code](/docs/reference/javascript/auth-signin#sign-in-using-third-party-providers)
|
|
|
|
```js
|
|
const { user, session, error } = await supabase.auth.signIn({
|
|
provider: 'google',
|
|
})
|
|
```
|
|
|
|
Add this function which you can call from a button, link, or UI element.
|
|
|
|
```js
|
|
async function signInWithGoogle() {
|
|
const { user, session, error } = await supabase.auth.signIn({
|
|
provider: 'google',
|
|
})
|
|
}
|
|
```
|
|
|
|
To log out:
|
|
|
|
```js
|
|
async function signout() {
|
|
const { error } = await supabase.auth.signOut()
|
|
}
|
|
```
|
|
