But something simple could work. Already you usually have a note under a password field, "Must contain at least 8 characters and at least one special character" or something to that effect. It could also have some note about "We suggest a randomly generated password from your password manager."
I'm not building this out so I don't need every hole poked in the idea, just seems like it could work.
They required the password to be changed monthly, have at least 10 characters, at least one number and at least one special character. On top of that – they locked out password managers and pasting. "We need to make sure you are the one logging in and not a hacker that hacked your password manager" they explained when I asked.
Out of spite I went for "Password12!" the first month and "Password123!" the month after, at which point I received an email from the IT department explaining to me that my choice of password was endangering the corporations security.
Many home users are pretty good about protecting important scraps of paper. The government gives us plenty to hold onto. Even if they’re a grandma that doesn’t understand all this password manager mumbo jumbo, they can deal with a notebook and be better off than using the same password on every site.
