To change your default Gmail account, you must sign out of all Google accounts on your device and then sign back in with the account you want as default first, as the first account you sign into becomes the default. This method works because Gmail does not have a separate "set default account" button inside its app; instead, the default is controlled by the order you sign in or by your device's mail settings.
Why your default Gmail account matters
If you manage multiple Gmail accounts, you have likely experienced the frustration of opening Gmail only to find the wrong account loaded, or accidentally sending an email from an account you did not intend. Your default Gmail account is the one that opens first when you launch the Gmail app or visit Gmail in a browser. It also determines which account Google uses by default for other services like Google Drive, Calendar, and YouTube when you are signed into multiple accounts. Setting the correct default saves you from constantly switching accounts and prevents mix-ups in your workflow.
How to change your default Gmail account on Android
On Android, the default Gmail account is set by the order in which you sign into your Google accounts. There is no option inside the Gmail app to designate a default account directly. To change it, follow these steps:
- Open the Gmail app on your Android phone or tablet.
- At the top right, in the search bar, tap your profile icon.
- Tap Manage accounts on this device.
- Tap the account you want as default, then tap the three-dot menu and select Set as default.
- Tap Remove account next to every Google account currently signed in. You must sign out of all accounts.
- Once all accounts are removed, tap your profile icon again.
- Tap Add another account > Google.
- Sign in with the account you want to be your default. Because it is the first account you sign into after signing out of all accounts, it will become the default.
- After signing in, repeat the process to add any other Google accounts you use. The first account you signed in with will remain the default.
If you later add more accounts, the first one you signed in with stays as the default. To change it again, you must repeat the sign-out-and-sign-in-first process. In the desktop Gmail settings, under 'Accounts and Import' > 'Send mail as', the current default email address is labeled 'Default' and you can click 'make default' next to another address to change it.
How to change your default Gmail account on iPhone and iPad
On iPhone and iPad, Google directs users to the device's Default Apps settings to make Gmail the default mail app. The exact menu path beyond that is not fully documented by Google, but the general approach is:
- Open the Settings app on your iPhone or iPad.
- Scroll down and tap Default Apps (or Mail in older iOS versions).
- Tap Mail and select Gmail from the list of available mail apps.
This setting controls which app opens by default when you tap an email link or compose a new message from outside the app. It does not change which Gmail account loads first inside the Gmail app itself. To set a specific Gmail account as the default within the Gmail app on iOS, you must use the same sign-out-and-sign-in-first method described for Android, as the Gmail app on iPhone and iPad also follows the first-signed-in rule for its own account order.
Adding another Gmail account to your device
Before you can set a different account as your default, you need to have that account added to your device. On Android, open the Gmail app, tap your profile icon in the search bar, then tap Add another account > Google and follow the sign-in prompts. On iPhone and iPad, open the Gmail app, tap your profile icon, tap Add another account, and sign in. Once the account is added, you can then use the sign-out-and-sign-in-first method to make it the default.
Frequently Asked Questions
Will changing my default Gmail account affect my existing emails and contacts?
No. Changing which account is set as default does not delete or alter your existing emails, contacts, or other data. All your information remains intact within each account.
Does changing the default account affect other Google services like Drive or YouTube?
Yes. The default Google account is used by other Google services when you are signed into multiple accounts. For example, if you open Google Drive after changing your default, it will open with the new default account unless you manually switch within that service. However, changing your default Gmail account will not have a direct impact on all services, but some services may be associated with a specific account and need separate updating.
Can I switch back to my previous default Gmail account?
Yes. Simply repeat the sign-out-and-sign-in-first process, signing into your previous default account first.
How do I know which Gmail account is currently set as my default?
On Android, open the Gmail app and look at the account name displayed at the top of the inbox. On iPhone and iPad, the account shown when you first open the Gmail app is your default.
Will changing names and labels on mobile affect my default account?
No. Changing names and labels on mobile only affects how your account appears and how messages are organized within that account. It does not change which account is set as default.
