If you want more than one person to use the same Alexa-enabled device, you can add multiple accounts by setting up an Amazon Household. Family members must have their own Amazon account, but once you’ve set up everything, you can jump from one account to another just by talking to Alexa.
With an Amazon Household, you and other members of the family can share the benefits of an Amazon Prime account, including access to Kindle ebooks and other digital content from Amazon on the web. For our purposes here, you can also grant certain people access to your home’s Echo devices and Alexa.
An Amazon Household can include up to two adults 18 years of age or older (this includes yourself), four teenagers 13-17 years old, and four children aged 12 and under. Children can use your Echo through a feature called Amazon Kids. Teenagers are able to order products on the web and stream video, but they won’t have access to your Echo or Alexa directly through their personal profiles.
