Unable to save username on kindle Fire using Silk Browser or Chrome about auth0-oidc-client-net HOT 2 CLOSED

Hi.

We don't actually support or test Fire OS which Kindle devices use in this SDK. While they are based on Android they deviate in many subtle ways - the browser being one of them. I'm kind of surprised it works at all, to be honest, but I can provide a little more background information if that will be of help.

On Android, this SDK calls the "Chrome Custom Tab" with the login URL and then waits for that API to complete. Despite the name Chrome Custom Tabs can be implemented by any browser not just Chrome and I know Firefox also supports it and presumably based on your screenshot Amazon Silk too.

However, what these browsers do once we pass it the URL is entirely outside of the control of this SDK - which is what Chrome Custom Tabs is all about (if we can't interfere we can't break functionality when the browser upgrades nor can malicious apps intercept what's being entered).

I can only assume that Amazon Silk has an issue with saving passwords in Chrome Custom Tabs mode - it looks like Chrome itself used to as well based on https://bugs.chromium.org/p/chromium/issues/detail?id=676814

One thing you could try is using SystemBrowser on Fire OS and see if it is happy to save passwords in that mode.

var auth0Client = new Auth0Client {
  new Auth0ClientOptions {
    // rest of config options
    Browser = isFireOS ? (IBrowser) new SystemBrowser() : new ChromeCustomTabsBrowser()
  }
}

I'm not sure how you can reliably detect Fire OS though.

No further response. Will re-open if that changes.
