Would like to recover or reset password of My Passport

I had a company restore my damaged notebook hard disk onto a WD My Passport external drive (not wireless) about a year ago. After installing a new SSD in my computer, I erased My Passport to use it as a back-up drive.

Today I wanted to use the drive to copy files from it to a friend’s laptop and it asked to be unlocked of course. Since I could not find the password, I tried to find out if I could reset it. No luck there either.
Please let me know how I can reset the user & password combination. Thank you.
