Account security: Enter Employee ID, password, MFA codes, banking changes and other sensitive account information only inside the official LiteBlue USPS.gov portal.
Use the official web portal
Open your browser and type liteblue.usps.gov directly. Avoid unofficial “LiteBlue apps” unless USPS itself links to them from an official domain.
Prepare your MFA method
If your primary authenticator is on the same phone, make sure you can switch between the browser and authenticator app. Keeping a backup method on a second device can help.
Browser troubleshooting
If a session behaves unexpectedly, close duplicate tabs, confirm your connection is stable, and restart the sign-in from the official home page rather than from an old bookmark to a deep sign-in state.
Public Wi-Fi caution
USPS security guidance advises avoiding public Wi-Fi or public computers when connecting to sensitive employee applications.
