What "default Gmail account" means and why it matters

Your default Gmail account is the one that opens automatically when you go to Gmail.com, and the one Gmail uses when you click "Sign in with Google" on other websites. If you have multiple Gmail accounts, your default is whichever one you signed into most recently — or the one Google remembers from your device.

Changing your default account is useful if you use Gmail for work and personal email separately, or if you share a computer and want your account to load instead of someone else's. The process differs depending on whether you are on a computer or phone, and whether you want to change it just for yourself or for everyone who uses that device.

Key Takeaways

  • Your default Gmail account is the one that opens when you visit Gmail.com, and it changes based on which account you signed in with most recently.
  • On a computer, you can switch accounts by clicking your profile picture in the top right corner and selecting a different account from the list.
  • To make a change permanent on a shared computer, sign out of all accounts first, then sign back in with only the account you want as default.
  • On a phone or tablet, your default Gmail account is tied to your device's main Google account, which you change in your device settings rather than in Gmail itself.
  • If you use Gmail on the web and want a different account to open automatically, clear your browser cookies or use a private browsing window.

Switching accounts on a computer (temporary change)

If you are on a Windows or Mac computer and have multiple Gmail accounts signed in, the fastest way to switch is to click your profile picture in the top right corner of the Gmail window. A menu appears showing all the accounts you are currently signed into. Click the account you want to use, and Gmail loads that inbox instead.

This change lasts only as long as you stay signed in. The next time you close your browser or clear your cookies, Gmail may load a different account by default. If you want the change to stick, you need to sign out of the accounts you do not want and keep only your preferred one signed in.

Making a change permanent on a shared computer

If you share a computer with others and want your Gmail account to open by default for you, sign out of all Gmail accounts first. Go to Gmail.com, click your profile picture, and select "Sign out of all accounts." Then sign back in with only the account you want as your default.

This works because Gmail remembers which account you signed in with last. By signing out completely and then signing in with only one account, you tell Gmail that is the one to load next time. If someone else uses the computer and signs into their own account, their account becomes the new default for them — but only if they sign out of yours first. If they just click your profile picture and switch to their account without signing you out, your account remains the default.

Changing your default on a phone or tablet

On an iPhone, iPad, or Android phone, your default Gmail account is the one linked to your device's main Google account. You cannot change this inside the Gmail app itself. Instead, go to your device settings and look for "Accounts" or "Google" (the exact name varies by phone type).

On Android, open Settings, tap Accounts, select Google, and choose which account you want as primary. On an iPhone, open Settings, scroll to Mail, then Accounts, and select the account you want Gmail to use by default. After you make this change, the Gmail app will load that account when you open it.

Using a private browsing window to test a different account

If you want to check a different Gmail account without changing your default, open a private or incognito window in your browser. In Chrome, press Ctrl+Shift+N on Windows or Command+Shift+N on Mac. In Safari, press Command+Shift+N. In Firefox, press Ctrl+Shift+P on Windows or Command+Shift+P on Mac.

In this private window, sign into the Gmail account you want to check. When you close the window, you are automatically signed out, and your default account remains unchanged. This is also useful if you want to avoid accidentally sending an email from the wrong account.

Clearing cookies if Gmail keeps loading the wrong account

Sometimes Gmail loads an old account even after you have signed out, because your browser remembers it in stored data called cookies. To fix this, clear your browser's cookies for Gmail.com specifically. In Chrome, click the three-line menu in the top right, select Settings, go to Privacy and Security, click Clear Browsing Data, check "Cookies and other site data," and type gmail.com in the search box. Then click Clear.

After you clear cookies, go to Gmail.com and sign in with the account you want as your default. Gmail will now remember this as your preferred account. If you clear all your cookies instead of just Gmail's, you may need to sign back into other websites you use regularly.

What happens when you sign in with Google on other websites

When you click "Sign in with Google" on another website or app, it uses your default Gmail account to create your login. If your default account is not the one you want to use on that site, click your profile picture after you sign in and switch to a different account before completing the sign-up. Some websites let you change which Google account is linked to your profile later, but it is easier to use the right account from the start.

If you have already signed up with the wrong account, you may need to create a new profile on that website using your preferred Gmail account, or contact the website's support to change the linked email address.

Frequently Asked Questions

Can I have two Gmail accounts open at the same time?

Yes. Sign into one account, then click your profile picture and select "Add another account." Sign in with your second account. Both will stay open in the same browser, and you can switch between them by clicking your profile picture. Your default is still whichever one you signed in with first, but you can switch when ready without signing out.

Why does Gmail keep loading my old account even after I signed out?

Your browser is storing a cookie that remembers your old account. Clear your browser's cookies for Gmail.com, then sign in again with the account you want. If the problem continues, try a different browser or a private browsing window to see if the issue is specific to one browser.

If I change my default account on my phone, does it change on my computer too?

No. Your phone and computer have separate default accounts. Changing your default on your phone only affects the Gmail app and Google services on that phone. Your computer's default stays the same unless you change it there too.

What if I forgot which account is my default?

Go to Gmail.com without signing in. If you are already signed in, click your profile picture and note which account name appears at the top. That is your current default. If you want to change it, sign out completely and sign back in with a different account.
