How to Google Sign-in your users in 5 minutes

A crucial aspect of any startup is providing users with the means to authenticate themselves. There are numerous methods available for achieving this, but if you're looking for a straightforward and effective option, Sign in with Google is often the first choice.

Integrating Google Sign-In is surprisingly simple with authentication providers. Personally, I'm quite a fan of Stytch for several compelling reasons:

• No Credit Card Required: they doesn't ask for your credit card information during the setup phase.
• Variety of Providers and Methods: It offers a wide range of alternative providers and authentication methods.
• Robust Documentation and Responsive Support: they provide extensive documentation, and their support team is quick to assist when needed.

How to Set It Up

1. Begin by visiting Stytch and creating an account. It is important that you select CONSUMER AUTHENTICATION.

2. In the sidebar, navigate to Configuration > API Keys and save the project_id and the secret somewhere secure, like your .env file.

3. Next, go to Configuration > OAuth and enable the Google provider. You'll receive a link, which you can use as the href attribute value in an <a> tag.

4. Lastly, instruct Stytch on where to redirect the user after completing authentication. Under Configuration > Redirect URLs, define a redirect URI for both signup and login. You can even have separate URIs for each.

Integration in Your Project

The minimum requirement is a simple HTML page that presents the <a> element with the href obtained in the previous section.

You'll also need an endpoint exposed to the redirect URI set in the previous section. This endpoint should be a GET method to which Stytch will send the authenticated client.

Stytch will attach two query parameters:

• stytch_token_type, with a value of oauth, which allows you to identify the authentication method used (though it can be ignored for this tutorial).
• token, a string that must be exchanged with the Stytch servers.

If you're using Node.js, the process is straightforward, as shown in this example:

import express from 'express';
import { Client } from 'stytch';

const client = new Client({
   project_id: process.env.PROJECT_ID,
   secret: process.env.PROJECT_SECRET,
});

const app = express();

app.get('/api/stytch/callback/signup', async (req, res) => {
   const token = req.query.token;

   const response = await client.oauth.authenticate({ token, session_duration_minutes: 60 * 60 });

   // Just an example
   db.users.add(response.user);

   res.cookie('token', res.session_jwt, { httpOnly: true });

   res.redirect("/dashboard");
});

// Omitting app.get("/api/stytch/callback/login") for brevity

app.listen(5173);

Give It a Try

To test it, run a live server and open the HTML page. Click the button to have your browser redirect you to the link provided by Stytch. Choose which Google account to use. The first time, it will invoke the signup endpoint, and all subsequent attempts will use the login endpoint
