According to the guys over at Ausdroid, multiple user support is on its way to Google Home, you can see what Google has to say below.
Google Home could be getting multi-user support - a feature that has always been desired by users.
One of the annoying things about most smart speakers is that they primarily work with a single account. If you haven't guessed it yet, it's multi-user login support.
As Google continues to improve its Home smart speaker, a new feature that you'll have been waiting for might just be around the corner.
Why Does Google Home Need Multiple Users' Support?
Google Home is one of the best smart home devices.
Previous rumors indicated that once it gets multi-user support, Google Home will also be able to distinguish between users's voices to automatically figure out who's speaking. Following the latest update, the Google Assistant is now saving any items you tell it to put on a list to Google Express, e.g. telling the companion "add bottled water to my list" would add that item to your Google Express list. There have been rumblings that Apple is trying to make Siri a more serious competitor to both Google Home and Amazon Alexa and we still don't know what they have up their sleeve. There's no mention how many users can be supported on one device or how switching of accounts will happen but at least it's there.
Another rumor is that Google plans on developing a hybrid version of the Google Home that is also a Google Wi-Fi hotspot. It'd be handy but we're now out of luck on that front, as are a number of regions around the world where Assistant is available but Google Express isn't.
We'll wait for an official announcement from Google about this new multiple user support.
