How to Reset Samba User Password Protection

[Chappy]

Hi, I'm new here and bought a Q10 Pro fitted with 8TB Barracuda.
I set it up a several months ago and saved its password in a 3rd party explorer app in my android phone to manage my media stuff. Today, I decided to connect it to my desktop to organize my stuff but apparently as expected I was prompt to enter my username and password. Problem is I already forgot my password and I couldn't view my saved password in the Mixplorer app in phone. I tried to reset my password but it requires me to input my old password which I've already long forgotten. Is there still a way to reset my password here? I don't want to setup any 3rd party app to use FTP instead of Samba, since it's already builtin the android it is much more optimized than a 3rd party app.

Any help is highly appreciated. Thanks!
