I have major trust issues: Go Figure.
I don't know how to trust passkey programs. So I have some antiquated but very hard to imagine passwords. And I have written them down in a notebook for my dotage and my heirs, in that order, I guess.

For online use I have Malwarebytes Free and AVG Free. They are both active and both try to sell me their pro versions which I may buy but have not yet. There don't seem to be issues with bad interactions between them. My overall understanding of what they do/ how they work is at a lower level than the crowd here, but it's an important subject so I'm trying to learn from you all.
