In the near future, an interesting option may work in Android devices - updating the system in the background. Now the user must manually enter the password after the first inclusion of a mobile device with an updated operating system and until this is done, the device will be in an idle state. The new feature will allow updating silently in the background and will not require user participation.
The new Resume on Reboot mode will save password and fingerprint data and provide it at the right time. The only point is that developers will have to make every effort to ensure that passwords and fingerprints are protected from theft by malicious users. At the moment, the mode is being tested on Pixel 4 and, most likely, the background update will be primarily implemented on it.
