Summary: I'm looking for a way to enable a form of "user" and "admin" modes on my Oneplus 7TPro. This takes the form of allowing the "user" to do 99% of tasks easily such as watching youtube or browsing Google, but it locks "admin" tasks such as disconnecting from mobile data, turning the phone off, accessing bank information, installing apps, etc behind an authentication such as biometric security. Similar idea to how SUDO works in Linux.
This idea comes from my real hatred of having to unlock my phone every time to use basic stuff like youtube or Google. I know modern phones have really fast biometric unlocking, smart unlock, and Google Assistant voice recognition but all that stuff just doesn't work for me enough to make it the solution.
Ideally the minimum scenario would be my phone not having any sort of screen lock at all, but I would still be able to use biometrics to sign into apps such as banking apps. Otherwise, the full functionality I'm looking for is to be able to lock multiple apps or system functions behind a fingerprint as well such as turning the phone, wifi, location, etc off (in the event its stolen) but still allow me to open my phone, use google assistant to access smart devices (with a pin for some), and use normal apps without the need to unlock my phone or use some form of smart unlock.
