Understanding Messenger Room
While increasing the prominence of video conferences due to COVID-19, Facebook introduced messenger rooms to make video calls for your friends and family. By using the Messenger app or by opening the Messenger website on your mobile phone or web browser, you can create large groups of rooms in video chat. Then you can send invitation links to your contacts and group chats on WhatsApp so that they can join these rooms, without having a Facebook account or Messenger app.
WhatsApp shortcuts allow you to access Messenger rooms which will be open in messenger app or web browser. Messenger is a separate app and website, so when you create a room, you need to log in with your Facebook account. Once you create a room, you have the option to lock your room to prevent new people from entering, or you can leave your room unlocked. The rooms are held outside of WhatsApp and the video chats in the Messenger rooms are not end-to-end encrypted.
To join an Unlocked room, you have to share a room link from your WhatsApp account. So, share this link only with trusted people. It is possible that someone forwards the link to other people. In that case, even if you don’t send the link directly, other people can join the room.
Facebook Messenger created its own feature messenger room. Since Messenger and other Facebook products do not support all available WhatsApp languages, some pre-filled Messenger messages or links may appear in a language other than that of your phone or computer. When you use Messenger Rooms or other Facebook products, your terms and their privacy practices apply to your use of these services.
