You may need to have multiple account with Google, most likely because you have you own personal account and do not want to mix up your personal cookies / browsing history / email etc with your work account.  You can do this in any browser, but the most secure way is to use Firefox with the Containers plugin.

Sign in to multiple accounts in a single browser 

If you have more than one Google Account, you can sign in to multiple accounts at once. That way, you can switch between accounts without signing out and back in again.

Your accounts have separate settings, but in some cases, settings from your default account might apply.

Add accounts

• 1. On your computer, sign in to Google.

  2. On the top right, select your profile image or initial.

  3. On the menu, choose Manage People and then Add account.

  4. Follow the instructions to sign in to the account you want to use.

Switch between accounts

• 1. On your computer, sign in to Google.

  2. On the top right, select your profile image or initial.

  3. On the menu, select the account you'd like to use.

Remove your account from the sign-in page

• 1. On your computer, sign out on a browser, like Chrome.

  2. Below the list of accounts, select Remove an account.

  3. Next to an account, select Remove 

  4. .

  5. Optional: If you've signed in on other browsers, like Firefox or Safari, repeat these steps for each.

Sign out

When you sign out of one account, you also sign out of all your accounts on that browser:

• 1. On your computer, go to a Google page, like www.google.com.

  2. On the top right, select your profile image or initial.

  3. On the menu, choose Sign out.

Accounts have separate settings

You can control your settings separately for each of your accounts. When you sign in to multiple accounts, account settings usually aren't shared between accounts. For example, your accounts might have different language settings or sign-in steps.

Sometimes settings might carry over

If you're signed in to multiple accounts at the same time, sometimes we can't tell which account you're using. For example, if you're signed in to two accounts and you open a new browser window, we aren't sure which account you want to use. In cases like these, Google might apply settings from your default account, like its Web & App Activity and Ads Personalization settings.

What a default account is

In many cases, your default account is the one you signed in with first. On mobile devices, your default account can vary depending on your device's operating system and the apps you use.
