We’re constrained to use the universal login page on our site within a webview in a 3rd party product, which causes a 403 for Google SSO. We can’t conditionally hide Google because existing users need to use Google to log in. The 3rd party product can’t just not use the webview because this is fundamental to their dapp browser feature, and other similar products use the same. Is there a way for auth0 to open an external user agent from within an embedded user agent in a native app?

The only way to comply with Google’s requirement would be to fully open your app in an external browser (which is something that the native app should be able to do on their side).
