Next-generation authentication security company Senstone (CEO Yoo Chang-hoon) is holding a limited-time giveaway event for its one-way dynamic authentication technology OTAC login function, which is expected to be of great help in preventing personal information leaks and financial accidents caused by credential stuffing, which is on the rise.

Sensestone announced that it will hold a special event for a total of 100 days until the end of this year to celebrate the 2nd anniversary of the launch of swIDch Auth, an all-in-one authentication solution that has obtained FIDO, the international standard for biometric authentication, and GS certification level 1, and will additionally give away the OTAC (One-Time Authentication Code) login function, the world's first patented one-way dynamic authentication technology.


Senstone's 'swIDch Auth' is a solution that has all the most powerful authentication security features, including user biometric authentication such as fingerprint, face, and iris, pattern authentication, simple PIN authentication, QR code authentication, encryption and electronic signature, private authentication, and server and administrator functions. It can be easily applied to systems and services that require strong multi-factor authentication (MFA).

It not only achieves FIDO simple authentication, the international standard for biometric authentication, but also obtains a first-class software quality certification (GS certification), ensuring both compatibility and stability.

During this special event, Senstone will additionally provide the 'OTAC login function' to all customers who purchase the swIDch Auth package.

OTAC is like ID and password. It provides a strong single-step multi-factor authentication (MFA) environment with only a one-time authentication code that changes each time without a primary identity verification process, enabling more secure and convenient authentication without compromising the user experience.

Moreover, by generating a one-time code that is never duplicated with another user without communication with the server, a more robust authentication security environment is built with minimal network and server resources without concerns about personal information exposure.

Senstone anticipates that this event, which offers FIDO biometric authentication, mobile OTP, and OTAC login capabilities, will provide a breakthrough in solving the recently emerging problems of smishing, voice phishing, and credential stuffing. The single-factor authentication (SFA) login method currently used by most web and app service sites, based on IDs and passwords, has numerous security vulnerabilities.

In particular, since many users use the same ID and password for each site, hackers who obtain illegally distributed account information are often helpless against credential stuffing, where they randomly enter the information into web or app service sites to steal users' information. Senstone explains that if each company and organization selectively implements each authentication function of swIDch Auth, an all-in-one authentication solution, according to its own system and service environment, it can prevent personal information leaks and financial accidents caused by credential stuffing, which is on the rise.

“We prepared this event to celebrate the second anniversary of the launch of swIDch Auth, which is currently being used by numerous financial institutions, universities, public institutions, and general companies, by additionally providing the OTAC login function, which has been recognized for its technology and security both domestically and internationally, so that more companies and organizations can build the most advanced authentication environment,” said Yoo Chang-hoon, CEO of Senstone. “Since security authentication incidents such as credential stuffing are increasing day by day due to the existing single authentication method based on ID and password, we hope to implement an authentication environment that is more powerful while not compromising the user experience with the swIDch Auth all-in-one authentication solution.”
