Manage multiple accounts
Many devices now support multiple online accounts. This means you’re in control of which account you use, and when. And even if you are signed in to multiple Google Accounts on the same device, personal information from one Google Account is not combined with information from any other Google Account, unless you decide to link those accounts together.
You can toggle between your Google Accounts easily and quickly, both on desktop and on mobile. For example, you can add a secondary Google Account when you’re signed in on your main account and switch back and forth between them. And on newer Google tablets with multi-user modes like the Nexus 7, it is simple for multiple accounts to be associated with one device. This makes it easy for different people in your family to check their email or access their apps without having to sign in and out. Once you have set up a primary account, you can easily add accounts in the device settings.
