I'm sorry, but I didn't quite understand your query. Could you please provide more details? Are you looking for a tool that allows students to test or quiz without needing to log in?

I recommend using Poll Everywhere. It's an interactive tool that allows you to engage students in real-time through live online polling, surveys, quizzes, Q&As, and word clouds. Students can participate using mobile devices or laptops, and they don't need to create an account to respond. This tool also integrates with PowerPoint, Keynote, and Google Slides, making it easy to add interactive elements to your presentations.
