I took this course at the same time as "Software Security". I really enjoyed Software Security, but Usable Security was horrible. The instructor is a really bad teacher, and she doesn't seem to know anything about computer science, she is just a psychologist. The videos a poorly made (most of the course are not even prepared and they are just 3 people openly discussing about something). The slides are useless (just some photos and 2-3 words per slide, and there are a lot of courses which don't even have any slides). The quizzes are useless, you could answer them without even looking at the course. The questions of the final exam do not have a clear answer (for instance: they think that a password with 8 random characters is hard to crack, but it would take only a few days with a brute force attack, and also they think that a user chosen 8 character password is more secure than a random one, which is wrong in my opinion). A lot of questions could be either true or false depending on the context and there is no formality in this course. I would not recommend it at all, but I took it as part of the cybersecurity specialization. Thankfully, the Software Security course was really amazing.
