I was wondering if there is a Duo app for using the "Duo push" on Ubuntu touch or if it's in the making at all. I know I would have to get the Android container set up and running but I'm a little weary of it. Has anyone had good experiences with it through the Android container?
Unfortunately, Duo is proprietary and does not document any way for third party apps to implement support for their push based 2FA system.
Also, Anbox does not include the proprietary Google Play Services components, and there's no bridge for notifications.
