description: Password-based authentication block for TanStack Start
|
|
---
|
|
|
|
<BlockPreview name="password-based-auth/auth/sign-up" />
|
|
|
|
## Installation
|
|
|
|
<BlockItem name="password-based-auth-tanstack" description="Supabase Client for TanStack Start" />
|
|
|
|
## Folder structure
|
|
|
|
This block includes the [Supabase client](/ui/docs/tanstack/client). If you already have one installed, you can skip overwriting it.
|
|
|
|
<RegistryBlock itemName="password-based-auth-tanstack" />
|
|
|
|
## Usage
|
|
|
|
Once you install the block in your TanStack Start project, you'll get all the necessary pages and components to set up a password-based authentication flow.
|
|
|
|
### Getting started
|
|
|
|
After installing the block, you'll have the following environment variables in your `.env.local` file:
|
|
|
|
```env
|
|
VITE_SUPABASE_URL=
|
|
VITE_SUPABASE_PUBLISHABLE_OR_ANON_KEY=
|
|
```
|
|
|
|
- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true) under App Frameworks or in your project's [API settings](https://supabase.com/dashboard/project/_/settings/api).
|
|
|
|
- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).
|
|
|
|
### Adding email templates
|
|
|
|
1. Add an [email template for sign-up](https://supabase.com/dashboard/project/_/auth/templates) to the Supabase project. Your signup email template should contain at least the following HTML:
|
|
|
|
```html
|
|
<h2>Confirm your signup</h2>
|
|
|
|
<p>Follow this link to confirm your user:</p>
|
|
<p>
|
|
<a
|
|
href="{{ .SiteURL }}/auth/confirm?token_hash={{ .TokenHash }}&type=email&next={{ .RedirectTo }}"
|
|
>Confirm your email</a
|
|
>
|
|
</p>
|
|
```
|
|
|
|
For detailed instructions on how to configure your email templates, including the use of variables like `{{ .SiteURL }}`,`{{ .TokenHash }}`, and `{{ .RedirectTo }}`, refer to our [Email Templates guide](https://supabase.com/docs/email-templates).
|
|
|
|
1. Add an [email template for reset password](https://supabase.com/dashboard/project/_/auth/templates) to the Supabase project. Your reset password email template should contain at least the following HTML:
|
|
|
|
```html
|
|
<h2>Reset Password</h2>
|
|
|
|
<p>Follow this link to reset the password for your user:</p>
|
|
<p>
|
|
<a
|
|
href="{{ .SiteURL }}/auth/confirm?token_hash={{ .TokenHash }}&type=recovery&next={{ .RedirectTo }}"
|
|
>Reset Password</a
|
|
>
|
|
</p>
|
|
```
|
|
|
|
### Setting up routes and redirect URLs
|
|
|
|
1. Set the site URL in the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings in the Supabase Dashboard.
|
|
1. Set up the route users will visit to reset or update their password. Go to the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings and add the `forgot-password` route to the list of Redirect URLs. It should look something like: `http://example.com/auth/forgot-password`.
|
|
1. Update the redirect paths in `login.tsx` and `update-password.tsx` components to point to the logged-in routes in your app. 1. Our examples use `/protected`, but you can set this to whatever fits your app.
