How to use hostedDomain option?

[Robo-Rin]

I'm a little unclear what this does and how to use it. I tried:

GoogleSignin.configure({
	webClientId: '[...].apps.googleusercontent.com',
	hostedDomain: 'somedomain.com'
});

but it doesn't seem to do anything.

Am I able to restrict which email domains can log in with this? Thanks!

I mentioned this in my StackOverflow question here.

I've figured out that it excludes the login from subsequent login attempts for email addresses that do not match the hostedDomain (somedomain.com), but it doesn't seem to prevent the initial login in the first place.

Is preventing the initial login of email addresses that don't match the specified hostedDomain possible out of box?

According to google docs you need to verify in the client as well.

So check if the user logged in is from the correct hostedDomain if not log him out. Then he should be prompt again to choose a different email.

Please re-open this issue if this is still a problem.

When a user enters its username manualy and it is not of correct doamin than can we login again
