I helped a friend set up an Instagram account for some project she was doing and discovered that her password system is a notebook. And do you know what? I didn't say anything. It's probably safer for her - it's shelved with other books, it doesn't have "passwords" on the cover and having showed her how to post on Instagram, I know that teaching her how to use Bitwarden (my manager of choice) is out of the question. She's younger than me, she's bright enough, but her life is mostly analog.
