The integration somehow overwrote my original OnePass account PIN such that I can't login to my account using either my United.com MP password or original OnePass PIN. Website error tells me to contact Mileage Plus service center. Still on hold for an agent after 3 hours..

The automated system via phone does report the correct combined redeemable miles balance but when prompted for PIN, the PIN that I enter registers as incorrect. Has anyone experienced a similar problem regarding account login?
