USPS: Use multifactor authentication? You’ll need to set a backup

June 26, 2025
The Postal Service is asking employees who use multifactor authentication to add a backup security method.

This will allow continued access to USPS systems and applications if the primary method becomes unavailable, such as when a smartphone is lost or not working.

Employees who already have a secondary multifactor authentication method do not need to take any actions.

Instructions for setting up a backup security method are on LiteBlue. Employee with questions can call the USPS IT Service Desk at 800-877-7435.
