Get started with authentication

When you create a project with serverpod create, email sign-in is already built in. The server is configured, the database is ready, and your app is connected to it. You only need to turn on the sign-in screen and run the app.

This guide walks you through that, then shows how to test signing up and signing in.

Sign-in with Serverpod

Prerequisites​

  • A project created with serverpod create on Serverpod 3.5 or later. For older projects, see Setup first to add the auth module.
  • The Flutter SDK installed, so you can run the app.
  • Docker installed and running, if your project uses a Docker Postgres. Projects on the embedded Postgres option don't need Docker.

Show the sign-in screen​

Your app already includes a sign-in screen. It is just turned off by default. Turn it on with two small edits to your app's main.dart.

First, import the screen:

import 'screens/sign_in_screen.dart';

Then show it as the home screen. In MyHomePage.build(), comment out the existing body: line and uncomment the SignInScreen block right below it, so it reads:

// body: const GreetingsScreen(),
body: SignInScreen(
  child: GreetingsScreen(
    onSignOut: () async {
      await client.auth.signOutDevice();
    },
  ),
),

That is the only change your app needs.

Start your project​

From the project root, start everything with one command:

serverpod start

This sets up the database and starts the server and your app.

The app opens on the sign-in screen. To create an account:

  1. Choose to create a new account, enter your email, and continue.

  2. Look in the server console for the verification code. While testing, it is logged instead of emailed:

    [EmailIdp] Registration code (you@example.com): 12345678

  3. Enter the code, then set a password to finish.

Once you are signed in, the app shows your content with a sign-out button.
