Microsoft Teams for families takes all those new features of Microsoft 365 for consumers and families and makes it a single hub to get all family things done in. Microsoft Teams for consumers and families is a chat, collaboration, and event planning hub for all family and friend interactions.
The Dashboard feature for Teams is also a unique feature for a family messaging app. The Dashboard is like a page for chats, and it is where all the Teams Chat information is stored and where users can go to access all the shared information. It has categories for media, location, calendar, files, Safe, and tasks.
Since Teams is also built from the foundation of the workplace, I think Teams for family and friends will have an equal amount of privacy and security. I think this is especially true since the work and family Teams are essentially the same but with different accounts.Currently, Teams is only available for mobile on iOS and Android. From my experience, it works great on iPhones but has a bit to go on Android.
