Assigning Passwords There are two prerequisites for assigning security level passwords in the HHP: The user must have admin privileges The password security scheme must be enabled To assign passwords, or simply to enter a display to see the current password assignments, follow this sequence: !!!!! SECURITY !!!!! Enter Password Install Passwords Pass stat (ENABLED) LEVEL2 LEVEL3 ADMIN PSWD PSWD PSWD 00012345 The screen directly above shows the initial default password assignments— the admin password is 12345, and the level-2 and level-3 password are null. At this point, all users have access to all HHP functionality except admin privileges. As admin, you have the ability to create passwords for level 2 and level 3, and you may also change or delete the admin password. Password Hierarchy The password security scheme imposes a set of priorities on the creation of level 2 and level 3 passwords: A level 2 password cannot be created unless a level 3 password already exists A level 3 password cannot be created unless an admin password already exists 164 Password Security For example, if you start out with the default admin password and no level 2 or level 3 passwords installed and immediately move the cursor up to the top line to enter a level 2 password, the HHP will not accept that password when you try to enter it. An error message appears on the bottom line of the screen: LEVEL2 LEVEL3 ADMIN PSWD PSWD PSWD 00DEF002 LEVEL2 LEVEL3 ADMIN E-Lowr PSWD PSWD PSWD 00012345 lvl paswd set 00012345 You must move the cursor down to the second line and enter a level 3 password before the level 2 password can be accepted. Creating a Level 3 Password Before you begin to create a level 3 password, make sure that an admin password has already been created. Then move the cursor to the second line of the screen—the field on the right side of the screen may be empty (if no level 3 password currently exists) or it may contain a character string (if there is already an existing level 3 password). To create a new password, or overwrite the old one, type in a character string that consists of 1 ... 8 alphanumeric characters from the HHP keypad. If you type less than eight characters, the HHP will fill all leading characters in the field with zeros. If you are overwriting an old password, the old character GM-MICR-HHP PRE
