No, we don't plan to implement a password manager. We have a ton of work ahead of us overhauling and/or replacing the legacy AOSP apps which was recently started for Contacts, Dialer and Messaging. It should begin shipping for those soon and Gallery will be replaced with a fork of a better app. We also have to continue improving our App Store, Auditor, Camera, PDF Viewer and Setup Wizard apps. There's also Vanadium, our privacy and security focused Chromium fork. That's a ton of app work to do without taking on making a lot more. There are already a lot of password managers. There was no hardened PDF Viewer remotely similar to what we provide and still isn't one, so that's why we made it and will continue the recently started major improvements to it. Our Camera app will also be getting more major improvements when the developer working on it is back in February.
