The more high tech the world gets, the more I like keeping many things low tech.
I use a laptop pc, and have a 2nd hard drive that I only use for banking and checking my 401k. no surfing with it, after I’m done with the financial work, it goes back on the shelf and use a another drive for playing on the internet.
I was doing online banking with a Commodore 128 but no longer feel secure with the practice. A virtue of the Commodore was that the software was firmware, i.e., on a ROM cartridge.
