reinstall nas (network attached storage)

i forgot login password to synology nas (actually I had a freelancer install it but I lost the passwords I did write down during the process). I googled "reset synology nas without losing data" and followed the steps. I see the existing folders in some synology software but apparently the prior login is conflicting with the new one so drive won't attach in a way for windows to use it. i have anydesk installed but am willing to install any screen sharing utility.
