SSenStone
SSenStone leads the next-generation paradigm of authentication security on the global stage beyond Korea. From pioneering a new realm of authentication security with OTAC to enabling more convenient and faster internationally certified biometric and mobile authentication implementations with swIDch Auth SDK, SSenStone is trailblazing the future of authentication security.


A new paradigm for user authentication and device authentication

OTAC(One-Time Authentication Code)
Based on the world’s first one-way dynamic authentication technology, OTAC technology, originally invented by SSenStone, provides more secure authentication for all digital identities even in the off-the-network environment. By reinventing authentication, SSenStone sets a new standard for authentication in cybersecurity beyond the limitations of existing authentication methods.
