...Google for Business Account
Business accounts provide a safe way to share management of your locations with multiple users. Business accounts are like a shared folder for your locations--a simple way to share access to a set of locations with coworkers. If you are currently sharing your account username and password with other users, you should transition to using a business account as a safer way to work together.
It’s a good idea to create a business account if:
You want to share location management with a co-worker, manager of one of your brands or regions, or an agency
You want to run location ad campaigns
To give the co-worker, manager, or agency access to a group of locations:
Create a business account.
Transfer all of your locations to that account.
Add the co-worker or agency employee as a manager or owner to the business account so that both parties continue to have access to all current locations and any locations created in the future.
