How to set password and accessibility?
Adding password protection or modifying accessibility options is easy with ProProfs Quiz School! While editing or creating a quiz, scroll to the bottom of the page and choose the accessibility tab. Once there, you can choose to make a quiz by adding a password.

Quiz Password
NOTE: While Quiz School itself is free, if you are planning to accept payment for quizzes on your site, you can issue the password to the user after the payment clears on your site. You can even post (embed) password protected quizzes back on your site.

Accessibility Options
You can also change other quiz options. “Accept name to start quiz” requires that users enter some sort of name before beginning a quiz whereas “Show answer after quiz completion” can hide the answers so that students do not cheat or copy off of completed quizzes. This feature can also find application in online interviews where you may not want to reveal answers to your proprietary question set to quiz takers. Another application area for hiding answers can be online tests & exams.
Most of the options are self-explanatory and all are reversible so you can play around and tweak them.

Type Password
Finally, save your quiz and watch as your quiz is now password protected with all important security options.
