If you have multiple Google Accounts that you want to use at the same time, you can add them to your Chromebook. When you add an account, you can use it with websites and Android apps.
At the bottom right, select the time.
Select Settings .
In the "Accounts" section, at the top, select your Google Account.
Select + Add Google Account.
Follow the on-screen steps.
Tip: You can also let other people sign in to your Chromebook using their Google Account.
If you no longer use a Google Account regularly on your Chromebook, you can remove the account.
At the bottom right, select the time.
Select Settings Accounts.
In the “Additional account” section, next to the account name, select Menu .
Select Remove this account.
Important: When you remove a Google Account from your Chromebook, it's only removed from the Chromebook. You're also signed out of any apps and websites where you used that account. The Google Account, including its data and settings, will still exist and be unaffected.
If you update your Chromebook to ChromeOS version 76 and up, you can also update your existing Google Accounts on your Chromebook. This lets you use them across websites and Android apps.
At the bottom right, select the time.
Select Settings .
In the “Accounts” section, at the top, select your Google Account.
Android apps, Chrome extensions, or websites that you use have access to your Google Account.
When you add a Google Account to your Chromebook:
Android apps: Your email and contacts are shared with Android apps that you have given permission to access your contacts.
Chrome extensions: Your info isn’t shared unless you grant permission to the extension for that specific account.
Websites: Your info isn't shared unless the website has a "Sign in with Google" option. If you choose to sign in with your Google Account, you get a list of permissions requested by the website. You can opt out of any of these steps.
