Hi Elmar,

Thank you for the feedback! I can definitely understand how some teachers would need a feature like this.

I've shared this feedback with our team so they can take this into consideration when planning future updates to our classroom tools.

In the meantime, if a student that you don't recognize joins your class, you can remove them via the Students tab on your teacher dashboard. You can find instructions for doing this here.

Thanks again! Please let me know if you have any additional questions!
