WD My Passport Ultra lost password but automatic unlocking activated?

I forgot my “wd my passport ultra” password. But “automatic unlocking” is activated. In this case I can learn how to decrypt the hdd without resetting it. Because I can only use it on my own computer. I can not use it on another computer because it wants a password.

Backup all data erase hdd and set it again should be best option for you?

I did it to myself. But there is no other option to back up and reset the hdd?

copy all data to PC. then erase WD my passport and set PW again. copy all data back to it.

Thank you. That is, hdd yi reset to zero no other way to remove the password.
