What is the DUO Mobile App and Is It Safe to Use?

DUO Mobile is a security application you’ll need to install on your phone when you sign up for your 3S Money account.

How does DUO Mobile work?

You'll receive a notification from your DUO Mobile app to approve when logging in or making a payment. You'll then be able to complete the necessary action.


What are the benefits of using two-factor authentication (2FA) with Duo?

Two-factor authentication (2FA) enhances security by adding an extra layer of protection beyond just a password. Here are its key benefits:

  • Increased security: Adds an additional layer of verification, significantly reducing the risk of unauthorized access.

  • Protection against password compromise: Even if passwords are compromised, attackers would still need the second factor (e.g., a code from a mobile app) to gain access.

  • Mitigation of phishing risks: Helps protect against phishing attacks by requiring a second form of authentication that is harder for attackers to replicate.

  • Enhanced user verification: Verifies the user's identity more reliably, as it requires something the user knows (password) and something the user has (e.g., a mobile device).

  • Regulatory compliance: Many industries and regulations mandate using 2FA to meet security and data protection standards.

Can I use my 3S Money accounts without DUO?

No, not currently.

For the security of our clients, DUO Mobile remains an essential part of operating a 3S Money account. It ensures that only the intended user can log into their account or confirm any payments.

It only takes a few seconds to accept the notification on your phone, but the additional security it provides is well worth it!
