ESET Secure Authentication4.2.1 - App Store

NOTE: Before installing ESET Secure Authentication, please note that the product requires server-side installation. This is a companion app and will not work independently. Contact your company‘s network administrator to receive your enrollment link.
ESET Secure Authentication is an easy-to-install, deploy, and manage, multi-factor authentication (MFA) solution for businesses. The additional factor-received or generated by the mobile app-complements and strengthens the standard authentication process and secures access to your company’s systems and data.

The ESET Secure Authentication app allows you to:
- Receive push notifications on your device that you can approve to complete authentication
- Generate one-time passwords to use alongside your username and password
- Add a new account simply by scanning a QR code
Supported integrations:
- Microsoft Web Apps
- Local Windows logins
- Remote Desktop Protocol
- VPNs
- Cloud services via AD FS
- Mac/Linux
- Custom apps
Multi-factor authentication is a combination of two or more security factors-“something the user knows” (e.g., a password), “something the user has” (such as a mobile phone to generate a one-time password or receive a push notification), and even “something the user is” (when approving push notifications via biometrics).
