Google Meet has undergone a number of changes recently to the way video calls can be made more secure for teachers and students. This video is a thorough guide to making sure your Meets are as safe as possible, by explaining everything you need to know, from the necessary admin-level settings, to the in-call settings like Host Controls and Quick Access settings.
