Google offers a built-in solution for managing multiple Google accounts: the account switcher. This is best for viewing multiple Google accounts in one browser window.
- While on google.com or any Google app or search results page, click on the icon or image for the account you’re currently signed in as (or log in with your primary account if you’re not already signed in).
- Click the Add Account button to sign in to your other Google accounts.
- After you’ve logged in with you other Google accounts, you can switch back and forth between accounts while using a Google app or tool.
