Google plans to use both Assistant and Duplex to make it easier to change stolen passwords on Chrome. Duplex is technology designed to handle tedious, multi-step processes on your behalf (like making a phone reservation). There's a version of this tech that can help you through online forms.
Now, Google Assistant and Duplex will make it easier to change compromised passwords on Chrome for Android. When you get warned about this issue on the mobile browser, an Assistant logo will show up next to the blue "Change password" button.
Tapping on this option will bring you directly to the change password form for the site or service in question. At the bottom of the screen, you'll see a sheet overlaid noting where you are in the process. Google Assistant will generate a suggested password you can accept and have automatically filled in. It will then confirm when you've changed your password successfully.
Google will save this password in your password manager, and at any time during this process, you can take over. The feature is coming to the US first, and other countries will get it in the "coming months."
