Abstract
A method and system for detecting and eliminating duplicate wireless mobile communications device Personal Identification Numbers (PINs) stored in user administration records associated with a server system is disclosed. The PIN of a wireless mobile communications device stored in a user administration record is checked against other existing user administration records, and if a duplicate of the PIN is detected, the PIN in one of the user administration records is reset. Duplicate PIN detection and elimination operations are preferably performed each time a new user administration record is created but may possibly be performed in response to selection of a particular user account, PIN or user administration record.
