Reset password without keeping synced like bookmarks, history, and passwords

Resetting your password without a recovery key deletes synced data (bookmarks, history, tabs, passwords) from Mozilla’s servers. Local copies on your device remain and can be re-synced upon sign-in.

Password reset without recovery key

Important for Sync users: If you reset your password without a recovery key, all encrypted data saved through Sync on Mozilla’s servers will be erased.
  1. Go to the Mozilla account password reset page (or click Forgot password? from the sign in page).
  2. Go to Mozilla Account Sign in.
    Sign in MA
  3. Click Forgot password?.
    Forgot password
    Note: This will also reset your account recovery key.
  4. On the Mozilla account password reset page, enter your email address and click Continue.
    Reset password
  5. An 8-digit confirmation code will be emailed to you. See I'm having problems confirming my Mozilla account for help confirming your account.
  6. Enter the confirmation code and click Continue.
    8 digit code
  7. If you have Two-Factor Authentication (2FA) enabled, you will be asked to enter the code from your application at this time.
    2fa code
  8. 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.

Reset Mozilla account password without keeping data

If you only need to reset your password and don’t need to recover any data, click the section below and follow the steps.

Password reset without saving current data

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

    new password
  7. 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.

Restore locally stored browser data after a Mozilla account password reset

Restore data on the same device

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

  1. Sign into Firefox with your new password.
  2. Click Sync now in the Firefox menu IG main menu.

Restore data on a new device

  1. Sign in with your new password on your original device first.
  2. Click Sync now in the Firefox menu IG main menu.
  3. 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

If your original device is unavailable or data was erased in a crash or reset, the locally stored data — like passwords, bookmarks, and settings — cannot be recovered.

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.
