Can't RE-activate password protection on My Passport $TB

I have a 4TB My Passport that is normally password-protected, but I accidentally clicked the auto-unlock box and now there is no password protection, and I can’t find any way to reactivate the password protect feature. Any suggestions? Thanks.
