I’m using the firebase/auth NPM package for user authentication with Google Login and Email/Password. It works great in most places, but some users in China and Iran can’t use my app because the requests to identitytoolkit.googleapis.com are blocked.

It seems like some VPNs also block these calls, which makes things even harder.

Is there any way to make firebase/auth send these requests through a proxy, like one under my own domain?

If that’s not possible, what would be a good workaround to let these users log in?

Thanks for your help!

I’m already using the “authDomain” config and it works fine, but it doesn’t solve the issue where identitytoolkit.googleapis.com requests are blocked.
