You can do the exact same thing in Windows, just think of the SysInternals Suite and its power. It’s just that people on Linux expect problems, while the overwhelming majority of people on Windows/MacOS is using their device expecting it to work and if it doesn’t they go do something else or buy another device.
Also this completely untrue notion that you cannot fix Windows or play around with its internals is very prevalent, to the point that it’s a meme, so people don’t even try.
Okay and now let’s get into threat modelling and risk management.
What is the purpose of a password manager? What are the possible threats against them, and what are those against singular passwords for services? What is the risk of each of those?
Just as much as CEOs (or any C-levels) deserve an exorbitant amount of pay for their ingenuity of sitting in meetings all day and basing decisions on pretty graphs made by others? Oh, and when the company “doesn’t do well” it’s the employees’ fault! Another round of layoffs WHOOO!
I want to insert my own logo into the boot process, and I want these ducking vendors to properly validate and assess their mother ducking software. But nooo, penetration tests and any remediations are too expensive for these pieces of bit. Why do it when you can just stick your dick in everyone’s face, right?
Password managers really are not hard to use. Also there’s stuff like the password manager built into iOS, for example, which you don’t even have to think about.
My comment about threat modelling was that you do not seem to understand the purpose of password managers. A way bigger problem for the average person online is password reuse, not targeted attacks against password vaults. That is the problem they solve.
