Don't keep your passwords and MFA on your computer at all.
As for my investment accounts, online banking, etc.. I keep that all in a secured & encrypted VM that I start up only when I need it, ensure it's secure (no malware, viruses, etc..) and then shut it down when I'm done and take it back offline.
By offline, it's on a separate, removable SSD.
Yes, I have a duplicate of it also.
There's your recovery plan. You're welcome.
(Let me know if I can help my brother from another mother. Always here for you.)
I may indeed be axing. <— (That’s a little Ghettobonics lingo, there.)
