As a host of a Room, you can enable guest entry, which allows users who do not have an account to participate in your Room
Enabling Guest Sign-In
As long as the Host of your Room has enabled guest sign-on while creating the Room, anyone with a link can join. To enable guest entry, set the 'Allow Join before Host' toggle to the right prior to entering the Room.
After setting the 'Allow Join Before Host' toggle, the Host of the Room can copy the link by clicking on the 'Copy Link' button and share it with anyone they want to join in on the fun!
