[Launch a new project](https://supabase.com/dashboard) in the Supabase Dashboard.
|
|
|
|
Your new database has a table for storing your users. You can see that this table is currently empty by running some SQL in the [SQL Editor](https://supabase.com/dashboard/project/_/sql).

<StepHikeCompact.Details title="Install the Supabase client library">
|
|
|
|
The fastest way to get started is to use Supabase's `auth-ui-react` library which provides a convenient interface for working with Supabase Auth from a React app.
|
|
|
|
Navigate to the React app and install the Supabase libraries.

<StepHikeCompact.Details title="Set up your login component">
|
|
|
|
In `App.js`, create a Supabase client using your [Project URL and public API (anon) key](https://supabase.com/dashboard/project/_/settings/api).
|
|
|
|
You can configure the Auth component to display whenever there is no session inside `supabase.auth.getSession()`
