Why LiteBlue requires MFA

USPS deployed MFA for LiteBlue in January 2023. The current public LiteBlue page states that employees must have MFA enabled and recommends registering at least two security methods.

Current MFA guidance

USPS has recommended Okta Verify, Google Authenticator and biometric authentication among its preferred backup options. Email verification was retired in 2024; options can vary based on an employee’s setup.

Set up a backup before you need it

A second method can reduce the chance of being locked out if a phone is lost, replaced or unavailable. USPS specifically encouraged employees to register a backup method on a secondary device.

Never share an MFA code

A legitimate support interaction should not require you to read an MFA code to an unsolicited caller. USPS warns employees that it will not call, text or email asking for passwords or MFA codes.
