What setting a default Gmail account does

When you have more than one Gmail account, your default account is the one Gmail opens to automatically, and the one that handles links you click in other apps and websites. Setting a default account saves you from signing out and back in every time you want to switch. It also prevents you from accidentally sending an email from your work account when you meant to use your personal one.

The default account is the one you're signed into when you open Gmail in your browser, or the first account you added to the Gmail app on your phone. You can change it at any time, and the change takes effect when ready.

Key Takeaways

  • Your default Gmail account is the one that opens automatically and handles email links from other websites and apps.
  • On a computer, you change your default by signing out of all accounts, then signing back in to the account you want as default first.
  • On an Android or iPhone, you can set a default account in the Gmail app settings under "Default email address".
  • If you use Gmail through a work or school domain, your organization may have locked the default account to prevent accidental sends to the wrong address.

Changing your default account on a computer

Open Gmail in your browser and look at the top right corner, where you'll see your profile picture or initial. Click it to see all the accounts you're signed into. If you only see one account, you'll need to add the other account first by clicking "Add another account".

Once you have both accounts visible in that menu, sign out of all of them by clicking "Sign out of all accounts" at the bottom of the menu. Then go back to Gmail.com and sign in again — but this time, sign in to the account you want as your default first. After you've signed in to that one, you can add your other account back by clicking your profile picture and selecting "Add another account".

Gmail will now treat the first account you signed back into as your default. When you click an email link from another website, it will open in that account. When you compose a new email, that account will be pre-selected in the "From" field.

Changing your default account on Android

Open the Gmail app and tap your profile picture in the top right corner. Select "Manage your Google Account", then go to the "Data & privacy" tab. Scroll down to "Data from apps and services" and tap "Gmail settings".

Tap "Default email address" and choose which account you want to use as your default. The change takes effect when ready. The next time you compose an email in the Gmail app, that account will appear in the "From" field.

Changing your default account on iPhone

Open the Gmail app and tap the menu icon (three horizontal lines) in the top left. Scroll down and tap "Settings". Select the account you want to make default, then tap "Default email address". Toggle it on.

If you have multiple accounts in the Gmail app, you'll see the toggle next to each one. Only one account can be the default at a time. When you turn on the default toggle for a new account, it automatically turns off for the previous default.

What happens when you click an email link from another website

When you click "Email us" or a mailto link on a website, your browser or phone opens Gmail and pre-fills the recipient's address. Which account it opens depends on your default. If your default account is set correctly, the email will open in the right account and you can type your message.

If it opens in the wrong account, you have two choices: compose the email there and then forward it to yourself in the correct account, or go back and change your default account before trying the link again. Some websites let you right-click an email link and copy it, then paste it into Gmail manually — this bypasses the default account entirely.

When your organization controls your default account

If you use Gmail through a work or school domain (an address ending in your company or school name rather than @gmail.com), your IT department may have set policies that lock your default account. This is a security measure to prevent employees from accidentally sending sensitive information from a personal Gmail account.

If you try to change your default account and the setting won't stick, or if you see a message saying the setting is managed by your organization, contact your IT support team. They can either unlock the setting or explain why it's locked. You can still use multiple accounts in Gmail — you just can't change which one is the default.

Troubleshooting: Your default account keeps changing

If you sign into a new account in Gmail and then close the browser, Gmail sometimes makes that new account the default on your next visit. This happens because Gmail treats "most recently signed in" as the default when you have multiple accounts.

To prevent this, always sign out of accounts you don't need open. After you've finished using a secondary account, click your profile picture and sign out of just that account — don't sign out of all accounts. This keeps your preferred default account active and prevents Gmail from switching it.

On phones, the Gmail app is more stable about keeping your chosen default. If it does change, go back to settings and re-select your default account. The app will remember it unless you uninstall and reinstall Gmail.

Frequently Asked Questions

Can I have a different default account on my phone than on my computer?

Yes. Your default account on your phone is set separately from your computer. You can set one account as default in the Gmail app and a different account as default in your browser. This is useful if you use your phone mostly for personal email and your computer mostly for work.

What if I forgot which account is my default?

On a computer, click your profile picture in Gmail and look at which account appears at the top of the menu — that's your default. On a phone, go to Settings in the Gmail app and look for the account with the default toggle turned on. You can also compose a new email and see which account appears in the "From" field.

Does changing my default account affect my contacts or email history?

No. Each Gmail account keeps its own separate contacts, emails, and folders. Changing your default account only changes which account opens automatically — it doesn't move or delete anything. All your emails stay in their original accounts.

Why does Gmail keep opening to the wrong account?

This usually happens if you signed into a different account more recently. Gmail sometimes treats the most recently used account as the default. Sign out of the account you don't want to use, then sign back in to your preferred default account. On a computer, make sure you sign out of all accounts first, then sign in to your default account first.
