I had mine on paper for years before i learned about Keepass. I trusted it more than a cloud based manager because someone would have to physically be in my room.
I am a lot more careful these days but that is not beyond the pale for a lot of folks haha
I was raised in the xp/windows 7 era. I switched to Arch Linux this year and have never been more satisfied with my computer. If i get stuck, the wiki and other nerds are happy to come to the rescue.
