Did LiteBlue ask you for a code after your password, and you didn’t know what to do? That’s called Multifactor Authentication (MFA) LiteBlue, and many USPS workers are having the same problem. It may seem confusing, but it’s just a way to keep your account and payroll info safe

Multifactor Authentication (MFA) LiteBlue

MFA is a safety step added to LiteBlue to help keep your account safe. It asks for something more than just your password, like a code or a phone check. This helps stop others from getting into your account, even if they know your password.

How Multifactor Authentication (MFA) LiteBlue Works

  • Login Step One: First, you type in your username and password like you always do.
  • Extra Security Check: After that, LiteBlue will ask you for a second thing, like a special code sent to your phone or email.
  • Get into Your Account: When both steps are done right, you can go into your LiteBlue account safely. LiteBlue MFA helps keep USPS employee accounts safe by stopping people who shouldn’t have access. It uses more than one step to check your identity, making accounts much harder to break into. Workers need to follow the MFA rules and tell their IT team if anything seems wrong to keep everything secure
