In 2023, we at Thetis recognized the growing need for robust cybersecurity measures in the financial sector. A prominent financial institution approached us to enhance their security posture and improve user experience by transitioning to passwordless authentication. This decision was driven by increasing threats of phishing attacks and the need for a more secure and user-friendly authentication method. The institution aimed to reduce customer friction, improve security, and lower operating costs.


The financial institution faced several key challenges:

  • Phishing Attacks: Traditional password systems were vulnerable to phishing attempts aimed at compromising user credentials.
  • User Experience: Customers experienced friction during the sign-in process, negatively impacting key business metrics.
  • Operational Efficiency: Managing and maintaining password systems was becoming increasingly cumbersome for the IT staff.

The Road to Passwordless: Enabling a Seamless User Experience

We evaluated several passwordless authentication methods with the financial institution before choosing FIDO2 and WebAuthn standards. This choice was based on the compatibility of our solutions with their existing infrastructure and our ability to provide a seamless and secure user experience.


We implemented Thetis’s passwordless authentication solutions, which included our FIDO2 security keys, biometric security keys, and contactless security keys. These solutions offered robust security and ease of use, supporting multiple connection methods (USB, NFC, Bluetooth).
