You can just use your own password manager and it wouldn't automatically do anything to apps on reinstall, right? Or a physical notebook, maybe.

I’d love to have my own password manager that syncs between all my devices without relying on a third party server, but I don’t know of one. Do you?

A physical notebook is so easily lost I wouldn’t even consider it.

I use KeepassXC and Syncthing. It's not a single password manager doing both the managing and syncing, but it works very well, and I sync between phone/laptop/desktop without any third parties.

Do they work on iOS?

Great name.
