For example, here are some white space #passwords with 80-bits security. There are 16 white space characters to choose from of varying widths, which means each of these below are 20 characters long, wrapped in quotes:
- "โ โโ
โโ โโโโโ โโโโ "
- " โโโโโใโโโโโโโโโโโโโ"
- "โโ โโโโโ
โโโโโโโโโโ "
- "โใโโโโ โ
โโโโโโ โ "
- "โโ โโโโโโโใโโ โ โใโ "
So, not only are there passwords you can't remember, now there are passwords you can't read!
22 unique non-graphical whitespace characters that I can reliably print during generation. That's ~4.459 bits of entropy per character.

Even zxcvbn-ts agrees that "โใโโ๏ปฟโ๏ปฟโฏ ๓ โโโ๏ปฟโโโโฏโโโโ แ โโโโโฏ" is a strong password.
