To increase the security of your Control Center user profile, you can add two-factor authentication (2FA). Adding 2FA to your user profile means you'll enter a six-digit code from an authenticator app after you type your username and password. If you want to change the device you use for 2FA or have issues wth your 2FA, you can re-enroll the two-factor authentication. Once you add 2FA to your user profile, you'll need to set up two-factor authentication the next time you sign in to Control Center. (If you're unable to sign in, a Control Center system administrator for your organization can re-enroll 2FA for your profile on your behalf.)
Two-factor authentication is required to view and manage services such as Lumen® Adaptive Network Security, Lumen® Adaptive Threat Intelligence, Lumen® DDoS Hyper®, Lumen® DDoS Mitigation Service, Lumen® Encrypted Wavelength, and NG9-1-1.
