Role Availability | ❌ Read-Only ❌ Analyst ✔️ Manager To protect your USM Central account, enable . MFA adds extra security because it requires multiple factors to authenticate a user, making it more difficult for an unauthorized person to gain access to the account. In USM Central, MFA provides a layered defense of two independent credentials: what you know (your user account name and password) and what you have (security token on your personal device). To use MFA in USM Central, you must have a mobile device that supports an Authenticator app. LevelBlue recommends the Google Authenticator app, which is available for iOS and Android devices. Google Authenticator implements two-step verification services using the Time-based One-Time Password (TOTP) algorithm and HMAC-based One-time Password Algorithm (HOTP) for authentication.
