Workstation MFA is a feature that allows LastPass Business admins to protect their users' workstations with a second layer of security. Once set up, users can log in to their workstations locally or via Remote Desktop Protocol (RDP) using their Windows account password, then they must authenticate using the LastPass Authenticator app (or YubiKey via the LastPass Authenticator app) on their mobile device for verification. Once authenticated, they are signed in to their Windows workstation.
