Make your passwords into not textualnon-textual ones. Like they can pick from a random set of images. Whatever is not easy to write down. Here is what Wikipedia has on it today:
"Non-text-based passwords, such as graphical passwords or mouse-movement based passwords.[70] Graphical passwords are an alternative means of authentication for log-in intended to be used in place of conventional password; they use images, graphics or colours instead of letters, digits or special characters. One system requires users to select a series of faces as a password, utilizing the human brain's ability to recall faces easily.[71] In some implementations the user is required to pick from a series of images in the correct sequence in order to gain access.[72] Another graphical password solution creates a one-time password using a randomly generated grid of images. Each time the user is required to authenticate, they look for the images that fit their pre-chosen categories and enter the randomly generated alphanumeric character that appears in the image to form the one-time password.[73][74] So far, graphical passwords are promising, but are not widely used. Studies on this subject have been made to determine its usability in the real world. While some believe that graphical passwords would be harder to crack, others suggest that people will be just as likely to pick common images or sequences as they are to pick common passwords."

For example if you used the faces method, you could use random stock images of people. So they can't just write down Steve from sales.
If the images are very similar and just show a plain portrait. They can also not write down something like the woman with the red scarf or the guy with big ben in the background.
