I need to reset my Mozilla account password, but I have synced passwords/bookmarks/etc...

You can use your account recovery key to complete your password reset and preserve your encrypted data in case you forget your password.

What is the difference between browser data and encrypted data?

Browser data

This data is stored on your computer or device. It includes things like your browsing history, passwords, bookmarks, and settings. As long as you still have access to the device and haven't erased the data, it will remain available.

Encrypted data

When you use Firefox’s sync feature, your data is stored on Mozilla's secure servers and encrypted for protection. This encrypted data can be accessed from any Firefox browser that device you sign into (on Desktop or Mobile) with your Mozilla account.

What happens to my browser data and encrypted data when I reset my password?

If you previously enabled an account recovery key and you use it to reset your password, you will retain access to your encrypted data on Mozilla servers.

However, if you forget your password and reset it without using an account recovery key, your encrypted data will be erased for security reasons. Your existing browser data remains unaffected and can be used to replace your encrypted data after you’ve reset your account password.

Resetting your password does not affect your subscriptions or payment information, as that information is stored separately.

Reset your password with your account recovery key

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

1. Go to the Mozilla Account password reset page (or click on "Forgot password?” from the signin page).
2. Enter your email address.

   

3. You will receive an 8-digit confirmation code via email. See Problèmes pour confirmer mon compte Mozilla for help confirming your account.
4. Enter the confirmation code and click Continue.

   

5. Enter your account recovery key.

   

6. Create a new password.

   

7. 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 logged in and backed up your data. This allows Firefox to retrieve your browser data, which is necessary for the recovery process.

1. Go to the Mozilla Account password reset page (or click on “Forgot password?” from the signin page).
2. Enter your email address.

   

3. Click on "Forgot your password?"
4. An 8-digit confirmation code will be emailed to you. See Problèmes pour confirmer mon compte Mozilla for help confirming your account.
5. Enter the confirmation code and click Continue.

   

6. If you have Two Factor Authentication (2FA) enabled, you will be asked to enter the code from your application at this time.

   

7. Create a new password.

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:
