Using Multi-Factor Authentication

Role Availability Read-Only Analyst Manager

To protect your USM Central account, enable multi-factor authentication (MFA) A method of access control in which a user is granted access only after successfully presenting several separate pieces of evidence to an authentication mechanism – typically at least two of the following categories: knowledge, possession, and inherence.. 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. AT&T Cybersecurity 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.
