@WAHa_06x36 @grote thanks for the explanation.
I feel like google did not think about real tools to help people beside make as hard as possible to use 3rd party software.
No anti virus (that windows has it), no isolation tools, app verifier, only google protect but not sure about it (is it enough) .

@grote Wow that is so hard.
I can feel the issue of avoiding people being tricked but with them I have some doubts.
Also why do I need to use biometrics?
