Restricting Google Domains

I'm working on replacing <GoogleOAuthProvider ...> in my React frontend with <KindeProvider ...>. <GoogleOAuthProvider ...> creates a popup window that restricts signin to Google accounts for a specific domain. In my case that's inrange.io I have configured Kinde with the same Google Client ID which I was using with <GoogleOAuthProvider ...>, but the signin prompt appears to accept signins from any domain. Can you help me understand why?

Hi @Martin, I'll ask my team and get back to you on this. Keep the questions coming. Hi @Martin, We are still looking into the best way to solve what you are after. I'll get back to you once I have more information. Hey @Martin, So assuming you you want to provide a login with Google method that restricts login to domains with inrange.io, you can achieve this by doing the following. If you want to restrict sign-ins to a specific domain in Kinde, you would need to implement this restriction in your application logic. For example, after a user signs in, you could check the domain of their email address and if it's not from the allowed domain (could also do a check to see if user.email is not null and if it ends in inrange.io), you could sign them out and show an error message. Here's a simple example of how you could do this in a React component:

import {useKindeAuth} from '@kinde-oss/kinde-auth-react';

const { user, logout } = useKindeAuth();

React.useEffect(() => {
  if (user && !user.email.endsWith('@inrange.io')) {
    logout();
    alert('You can only sign in with an @inrange.io account');
  }
}, [user, logout]);

import {useKindeAuth} from '@kinde-oss/kinde-auth-react';

const { user, logout } = useKindeAuth();

React.useEffect(() => {
  if (user && !user.email.endsWith('@inrange.io')) {
    logout();
    alert('You can only sign in with an @inrange.io account');
  }
}, [user, logout]);

In this example, useKindeAuth is a hook provided by Kinde that gives you access to the current user and a logout function. The React.useEffect hook runs whenever the user or logout changes. If there's a user and their email doesn't end with '@inrange.io', it logs them out and shows an error message. Please note that this is a simple example and you might want to handle this in a different way in your application, depending on your specific requirements and user experience considerations. Let me know if you have any questions.

If you want to restrict sign-ins to a specific domain in Kinde, you would need to implement this restriction in your application logic.

I think it should be possible to implement this directly in the Google login form. This is certainly possible with the <GoogleOAuthProvider ...>. Specifically, using <GoogleOAuthProvider clientId="580941988699-9mtsjs3att3dghs3sciclo4e9n5e473p.apps.googleusercontent.com"> and

      <GoogleLogin
        onSuccess={logUserIn}
        onError={errorMessage}
        theme="filled_blue"
        logo_alignment="center"
        size="large"
        shape="pill"
        useOneTap={false}
        hosted_domain="inrange.io"
      />

      <GoogleLogin
        onSuccess={logUserIn}
        onError={errorMessage}
        theme="filled_blue"
        logo_alignment="center"
        size="large"
        shape="pill"
        useOneTap={false}
        hosted_domain="inrange.io"
      />

results in the Google sign in box with the inrange.io domain pre-filled in. Would it be possible for Kinde to support passing through hosted_domain through to the Google login?

Hey @Martin, Let me get back to you on this. Hey @Martin, We are looking into a solution on the Kinde end with hosted_domain. I will keep you informed. Hi @Martin, We have built a prototype that uses hosted_domain, but this is a hint and does not retrict sign-ins to Google with that domain (i.e. you can still sign in with Google with any domain). Does this hint satisfy your needs at the moment?

See the attached recording

Martin•7mo ago

That's really interesting! I didn't know that this was just a hint. However, I'd still love to be able to show that hint if possible. That demo looks like exactly what I'm looking for. Thanks for moving so quickly on this!

Oli - Kinde•7mo ago

No worries, there is a PR for the hint. Ill let you know when its live.

Martin•7mo ago

Perfect, thanks!

Oli - Kinde•7mo ago

Hey @Martin, We are revisiting the PR to make the hint for all those social providers that accept a hint, so it will be a bit longer than initially expected before this change is live and you can give a hint to Google sign-up/in. Is this blocking you from going live with Kinde?

Martin•7mo ago

Thanks for the update. This isn't blocking for us. Looking forward to getting this new feature 🙂

Oli - Kinde•7mo ago

Noted. I will let you know once this is live.
