When a password is generated with "I", "l", "1", and other lookalike characters, it can be confusing to read with the current font choice, since it uses a sans-serif font.
This isn't as big of an issue with words as passwords, but it still causes some confusion when looking at the generated phrase. For example, if the phrase is "StillIllness" (StillIllness), a serif font would be better than a san-serif font to display the words and phrase generated.
