Changing Unlock Password

When I set up MyPassport Ultra I set it up to automatically unlock. Now that I’m carrying the drive with me to different work sites, I want to change it to have me input the password when needed. Can’t seem to find how to do this. Any help would be appreciated.

TIA

Hi, in the WD Security software, remove the password protection and add it again, make sure not to check the “Auto Unlock” from the app.
