Hi Carlos, In my testing, the password is a one-time password which you define when you ran mokutil. If you are importing then you'd run mokutil --import <somefile>.der If you are deleting then you'd run mokutil --delete <somefile>.der Both would prompt you to specify the one time password and the confirm it. When you reboot the MokManager comes up and you enter that one time password. Sometimes MokManager just asked for the entire password, other times it would ask for the character at several different positions in the password. The next time you ran mokutil --import or mokutil --delete you could specify a different password and when rebooting and getting MokManager prompt you would then use that new password. I have seen various articles/etc about this and some did say the root password, but that does not appear to be true from my testing as it works exactly as I described and I have done this MANY times trying to sign and get the kernel to load the vmware compiled modules. Hope that helps! P.S. I believe the USA kb layout requirement may be true. Joe
