I switched to one of those deleted-in-30-days emails because if I manage to get locked out of my fucking Kiwifarms account, then I'm exceptional and deserve the meagre loss of my "The Line, Held" trophy points.
Also I write down sensitive information on sticky notes in books, and then when disposing of them I hand-shred and recycle the pieces over an inconsistant period of time. Nobody's going to flip through "Noh plays of Japan" for passwords, and the FBI boogieman and an idiot hobo rummaging through my trash will be equally unable to get all the pieces, let alone put them together.
I also have a handful of passwords I use based on how important an account's security is, instead of just one for everything or a special one for each account. So if you have my Kiwifarms password, congrats, you can also steal the $1.37 left on my Dunkin Donuts account.
