LiteBlue Security Tips and Phishing Protection
Learn how to protect USPS LiteBlue credentials from fake login pages, phishing messages, and unsafe browsing habits.
Check the Address
Always verify that the login page belongs to the official USPS domain before entering credentials. Fraud pages may use similar words, colors, or logos to look convincing.
When in doubt, close the page and type the official address yourself.
Protect Your Password
Use a strong unique password, never share it, and avoid storing it in plain text. If you suspect someone knows it, reset it through the official recovery path.
Watch MFA Prompts
Unexpected MFA prompts can mean someone is attempting to access your account. Do not approve prompts you did not initiate.
