Yes.  Google supports multiple account sign-in in most of its most popular services, including: Mail, Contacts, Calendars, Drive and Docs.

Sign in to multiple accounts at once

If you have more than one Google Account, you can use multiple sign-in to switch between accounts without having to sign out and back in again. For example, if you have one Google Account for personal use and a different Google Account for business, you can easily switch between the two within the same browser (like Chrome or Firefox) using multiple sign-in.

Add your Google Accounts

  1. Sign in to Google.
  2. Click your profile photo or email address at the top-right corner of the page.
  3. Click Add account from the drop-down menu.

Ways you can use multiple sign-in

Here’s an example of different accounts you might own and use with multiple sign-in:

Account When you'd use it
Personal To send emails to friends, search for things you’re interested in, and manage your personal schedule.
Business To send emails to coworkers, do business related searches, and schedule business meetings with coworkers and clients.
Sports To send emails to teammates, search for sports equipment, and keep a calendar of your team practice and game schedule.

Multiple sign-in is most useful on a device where you won’t need to sign out of your account for others to use it. If you share the device with other people, check out the other options to securely sign in to Google

Ways to tell your accounts apart

You can tell your different accounts apart by the email address associated with them or by setting up the following:

Accounts have separate settings

Account settings are not automatically shared between different accounts when you use multiple sign-in. That means you can have separate settings for each account when using services like Search History or Google Now. For example, you can have Search History turned on for one account, but turned off for another account.

Places multiple sign-in doesn’t work

Multiple sign-in doesn't work with some Google products and mobile versions of Google products. For those places multiple sign-in doesn’t work, you will be automatically signed in to the first account you signed in to on that browser. For example, multiple sign-in won’t work with:

Some Google products and mobile versions of Google products do not support the use of multiple accounts in the same web browser. Instead, they default to the first account that you signed in to from your current browser.

  • Adwords
  • Analytics
  • Blogger
  • Picasa

Google Drive supports multiple sign-in, but works differently than other products.

For those places you can’t use multiple sign-in, you have a few options:

  • Use different browsers for each of your accounts. For example: Google Chrome for your business Google Account and Mozilla Firefox for your personal Google Account. Not sure what a web browser is? Find out.
  • Use Google Chrome's incognito window to sign in to your second account. Be aware that your browsing history won’t be saved when you use the incognito window.
  • Use multiple profiles on Chrome. Learn more.
  • Sign out of all your Google Accounts and then sign in to the account you want to access.

Signing out

When you sign out of any account, you’ll be signed out of all your accounts on that browser. If you want to use multiple sign-in again, follow the steps in the “Add your Google Accounts” section above again. 
To sign out of all accounts:

  1. Go to your Google Account page.
  2. Click your profile photo or email address at the top right of the page.
  3. Click Sign out from the drop-down menu.
