Security Strategy for Laptops

[kalpana]

I am trying to create a security strategy for two laptops, mine and my wifes. Ideally, I want increased security when our laptops are away from our home.

I have a mounted NAS device that is in a secure location. So, if the laptop is say stolen, the NAS device would not mount and browser password would not be enabled.

I use Bitwarden on laptop, with a Brave plugin. I tried the AppImage version of Bitwarden but it has no browser integration on linux.

My wife uses Firefox. I tried to use the master password for her but she complains.

Strategies?
