What "default account" means and why it matters
When you have more than one Gmail account, your default account is the one that opens automatically when you go to Gmail.com or click a Gmail link. It's also the account Gmail uses to send emails unless you switch to a different one before hitting send. Changing your default account takes about 30 seconds and lives in your account settings, not in your browser.
This is different from your browser's default — even if Chrome opens to your work Gmail, your personal Gmail could still be set as your default in Google's system. The two settings work independently, which is why you might need to change both.
Key Takeaways
- Your Gmail default account is set in Google Account settings, separate from your browser's homepage or default search engine.
- To change it, sign into the account you want as default, go to myaccount.google.com, and select it as your primary account in the account settings.
- If you're signed into multiple Gmail accounts at once, you can switch between them using the profile icon in the top right without changing your default.
- Your default account is what Gmail uses to send mail and what opens when you click Gmail links from other websites.
How to set your default account in Google Account settings
Start by signing into the Gmail account you want to be your default. Once you're logged in, go to myaccount.google.com in your browser's address bar.
On the left side of the page, click Personal info. At the top of that section, you'll see your account name and email address. If you have multiple Google accounts, this is where you can see which one you're currently in. Look for a button or link that says You or shows your account picture — click it to see options for managing your accounts.
Select the option to make this account your primary account. Google may ask you to confirm your choice. Once you do, that account becomes your default for Gmail, Google Drive, Google Photos, and other Google services.
Switching between accounts without changing your default
If you use multiple Gmail accounts regularly but only want one to be your default, you don't have to change settings every time. Instead, sign into all your accounts at once and switch between them using the profile icon.
In the top right corner of Gmail, click your profile picture or initial. You'll see a list of all accounts you're signed into. Click the one you want to use right now. Gmail will switch to that account for this session, but your default account stays the same — the next time you close and reopen Gmail, your default will load first.
This approach is useful if you have a work account and a personal account, or if you manage multiple projects under different Gmail addresses. You can stay signed into all of them without confusion about which one is "primary."
What happens when you change your default account
Once you set a new default, Gmail will open to that account the next time you visit Gmail.com or click a Gmail link from another website. Any emails you send will come from that account unless you manually switch to a different one before hitting send.
Your other accounts don't disappear — they stay signed in if you were already signed into them. You're just changing which one loads first and which one Gmail assumes you want to use.
If you use Gmail on your phone, the default account setting applies there too. The Gmail app will show your default account first when you open it, though you can still switch to other accounts from the menu.
Changing your default on different devices
The default account you set in Google Account settings applies across all your devices — phone, tablet, and computer. You don't have to change it separately on each one.
However, your browser might have its own default. If you use Chrome and want Gmail to open to a specific account, you can also set Chrome's homepage to that account's Gmail URL. This is a browser-level setting, separate from your Google Account default, and it only affects that particular browser on that particular device.
If you switch devices or browsers, the Google Account default follows you (because it's tied to your account), but the browser default does not (because it's tied to that browser).
Troubleshooting: Gmail keeps opening to the wrong account
If you've changed your default but Gmail still opens to a different account, check whether you're signed into multiple accounts. When you're signed into more than one, Gmail sometimes defaults to whichever one you used most recently, overriding your account settings.
To fix this, sign out of all accounts except the one you want as default. Go to myaccount.google.com, click your profile picture, and select Sign out of all accounts. Then sign back in with only your default account. This resets which account Gmail considers "active."
If you're using a shared computer, also check whether someone else has set a different default account. Each Google Account has its own default setting, so if your partner or roommate uses the same computer with their own Gmail, their default won't affect yours — but you'll need to be signed into your account to change it.
Frequently Asked Questions
Can I have two Gmail accounts open at the same time?
Yes. Sign into your first account, then click your profile picture in the top right and select Add another account. Sign into your second account. Now you can switch between them using that same profile menu without signing out. Your default account is still whichever one you set in Google Account settings.
Does changing my default Gmail account affect my browser's homepage?
No. Your Gmail default and your browser's homepage are separate settings. If you want Gmail to open to a specific account when you open your browser, you'll need to set your browser's homepage to that account's Gmail URL separately. This is done in your browser settings, not in Google Account settings.
What if I forgot which account is my default?
Go to myaccount.google.com and look at the account name and email shown at the top of the Personal info section. That's your default account. If you're signed into multiple accounts, make sure you're viewing the right one by checking the profile picture in the top right corner.
Will changing my default account delete any emails?
No. Changing your default account only changes which account opens first and which one Gmail uses to send mail. All your emails in every account stay exactly where they are. You're not moving or deleting anything.
Can I set a different default account on my phone than on my computer?
No. Your default account is tied to your Google Account, not to a specific device. If you change it on your computer, it changes on your phone too. However, you can still switch between accounts on your phone using the menu, just like on your computer.
