digital signage GLOSSARY

Two-Factor Authentication

Two-Factor Authentication (2FA) is an authentication method that requires two independent verification factors — typically something the user knows (password) plus something the user has (one-time code on a phone, hardware key, biometric). 2FA dramatically reduces the risk of unauthorized access, even when passwords are compromised.

In digital signage, 2FA matters because the platform controls what appears on screens visible to the public, customers, employees and stakeholders. An unauthorized actor with platform access could deface displays, leak data, or push malicious content. Livesignage includes 2FA on the Enterprise and Phygital license tiers, with support for TOTP authenticator apps, SMS one-time passwords, and SSO integration through the customer's identity provider — and every login is recorded in the audit trail.

Use Cases

2FA is the security baseline for organizations operating signage as an enterprise system:

- Banking and financial services: regulated environments requiring strong authentication.
- Healthcare: clinical and patient-facing signage with HIPAA-grade access control.
- Public sector and government: civic signage with mandated security policies.
- Multi-site retail and franchises: protecting brand-critical content across hundreds of users.
- Corporate and enterprise IT: signage integrated with central SSO and identity systems.
