"This policy setting allows you to specify how many times a user may enter an incorrect device lock password before being required to enter a code word. This policy can prevent a local device wipe caused by an accidental password entry.  If you enable this policy, then you can set the "Code word frequency" value to specify the number of incorrect password attempts the user is allowed to make before being required to enter a codeword. It is recommended that you set this value to a number less than the number of incorrect password attempts that cause the device to be wiped.  If you disable this policy then the user is not asked to enter a codeword after incorrect password attempts.    If you do not configure this policy, then the existing device wipe setting on the device remains in effect."
