If you know your Private Key, you can change your Trading Password using the Private Key.
Please check and follow the steps below:
1. From the main page of MARBLEX Wallet, press the “Settings” tab at the bottom right corner.
2. Next, press “Verification and Security”.
3. Press “Change Trading Password”.
4. Enter your Private Key and press confirm to change the Trading Password.
But, if you lost your Trading Password without verifying the Private Key, you will not be able to recover it. You need your original Trading Password to verify the Private Key.
Please keep in mind that, as much as we would like to help you recover it, we do not store anyone's Trading Password.
If you can't remember your Trading Password, unfortunately, you might not be able to use the service.
We sincerely apologize for being unable to assist you in this matter.
