Interestingly, Coursera uses these timings to authenticate that it is really you taking a quiz for one of their courses.

Most of the Coursera courses I took gave quizzes that were mainly multiple choice, this limiting the availability of a keystroke-corpus to identify the user.

Curious if this has changed recently to warrant this comment as the last course I took was a while ago.

Yeah, they're still multiple choice. They have you type a phase before you take the quiz.

At the start of the course they have you type the phrase once or twice to get your cadence and then take your picture afterwards.
