Change your Mozilla account password

If you are signed in to your Mozilla account, follow these steps to change your password:

Change your Mozilla account password while signed in

If you can sign in to your Mozilla account, you can change your password by following these simple steps:

Go to Mozilla account Sign in.
Sign in with your current password.
In the Security section, next to Password, click Change.
Enter your old password, then your new password.
Click Save to complete the change.

Reset your Mozilla account password

If you can’t sign in to your Mozilla account, you still have options to reset your password and regain access. Depending on your account setup, certain methods can help you retain your saved data. Select the option that best describes your situation to follow the appropriate steps.

Reset your password if you're locked out of your account

If you can't sign in to your account, you can reset your password by following these steps:

Go to Mozilla Account Sign in.
Click Forgot password? and follow the prompts.

Note for Sync users: Resetting your password will erase the encrypted data (like bookmarks and logins) on Mozilla's servers if you don’t have an Account Recovery Key. But don't worry, the data stored on your device won't be affected.

Reset your password with sync data

If you have an account recovery key, you can use it to reset your password without losing data stored through Sync. Click the section below to see the steps.

Use a recovery key to reset your password

If you forgot your password, follow these steps to reset it:

Note: This will also reset your account recovery key.

Go to the Mozilla account password reset page (or click Forgot password? from the sign in page).
Enter your email address and click Continue.
You will receive an 8-digit confirmation code via email. See I'm having problems confirming my Mozilla account for help confirming your account.
Enter the confirmation code and click Continue.
Enter your account recovery key.
Create a new password.
After resetting your password, a new account recovery key will be generated for you.

Recovery keys expire after every use, so it’s important to replace the previous one you had saved.

Reset your password without your account recovery key

To perform this password reset without a recovery key, it’s best to reset the Mozilla account from the same device where you last signed in and backed up your data. This allows Firefox to retrieve your browser data, which is necessary for the recovery process.

Go to the Mozilla account password reset page (or click Forgot password? from the sign in page).
Enter your email address and click Continue.
An 8-digit confirmation code will be emailed to you. See I'm having problems confirming my Mozilla account for help confirming your account.
Enter the confirmation code and click Continue.
If you have Two-Factor Authentication (2FA) enabled, you will be asked to enter the code from your application at this time.
Create a new password.

Warning: If you are a Sync user and likely to have data stored on Mozilla’s servers, a warning will appear informing you that your encrypted browser data may be deleted. This applies only to data stored on the servers and will not affect the data stored locally on your device.

For users with a recovery key configured

If you have a recovery key but clicked Can't find your recovery key?, you will see a slightly different message regarding data recovery. In this case, you will be prompted with a screen guiding you to retrieve your recovery key or continue without it.

For users with a recovery key who clicked 'Can't find your recovery key?'

For users without a recovery key

Restore browser data after a Mozilla account password reset

If you’re using the same device, your data browser data is already safe as it is stored locally. Simply sign in to your Mozilla account in Firefox using your new password and select Sync now from the Firefox application menu . If you’re switching to a new device or using an older version of Firefox that doesn’t support sync, transfer your data using the Firefox backup assistant.

Restore data on the same device

If you’re using the same device, your data is already safe!

Sign into Firefox with your new password.
Click Sync now in the Firefox menu.

Restore data on a new device

Sign in with your new password on your original device first.
Click Sync now in the Firefox menu.
Sign in with your new password on the new device and sync.

Move data to a new device or use an older Firefox version without sync support

If you are moving to a new device or using a version of Firefox that no longer supports sync, you can transfer your browser data via the Firefox backup assistant as long as you still have your original device.

Recover data without the original device or after data loss

Regrettably, if your original device is unavailable or the data was erased during a crash or wipe, there is no way to restore your passwords, bookmarks, etc.

Reset Mozilla account password without browser data

To reset your password without restoring browser data (e.g., passwords, bookmarks, or settings), click the section below and follow the steps to complete the process.

Reset your password

Go to the Mozilla account password reset page (or click Forgot password? from the sign in page).
Enter your email address and click Continue.
An 8-digit confirmation code will be emailed to you. See I'm having problems confirming my Mozilla account for help confirming your account.
Enter the confirmation code from the email and click Continue.
If you have Two-Factor Authentication (2FA) enabled, you will be asked to enter the code from your application at this time.
Follow the on-screen instructions to create a new password.
After signing in with your new password, you’ll need to sign in again on all of your devices.

Note for Sync users: We recommend creating an account recovery key. This allows you to securely restore your information (such as passwords, bookmarks and settings) in the event you forget your password again. This does not include subscription related information, as that is stored separately.

Difference between browser data and encrypted data

Browser data includes information such as browsing history, bookmarks, saved passwords, and settings, stored directly on your device. This data remains accessible as long as you have the device and haven’t removed the data.
Encrypted data is created when you use Sync. You can choose to sync selected data, which is then stored on Mozilla’s servers in an encrypted form to ensure privacy and security. You can access encrypted data from any device where you’re signed in with your Mozilla account.

Impact on data after a password reset

If you reset your password using a recovery key, you will retain access to encrypted data. Without a recovery key, encrypted data on Mozilla’s servers is erased for security purposes, while browser data on your device remains unaffected, allowing you to restore your settings.

Note: Resetting your Mozilla account password doesn’t impact subscriptions or payment details, as these are managed separately.
