The term Subsidy Password is used by Motorola to refer to the 8-digit (or 16-digit code for newer phones such as the Motorola K1) unlock code necessary to remove the operator lock (also known as subsidy lock) from Motorola cell phones. This code is randomly assigned to individual cell phones by the OEM (Motorola) on request of the mobile service operator, and prevents use of a particular phone on a cellular network other than that to which the phone was originally sold
