swIDch Auth SDK provides various functions verified by FIDO alliance.
Simpler than using a password while also being more secure, we use FIDO
authentication technology to establish a robust authentication environment in
cyber security.

swIDch Auth SDK provides a mobile OTP function that runs on a mobile
application. With the use of PIN inputs or fingerprint recognition, mobile OTP
generates a one-time OTP number that provides the same level of robust
security as standard OTPs.

OTAC login

OTAC login

swIDch Auth SDK provides login functions based on swIDch’s powerful
authentication technology, OTAC (One-Time Authentication Code). Even
when the client (service user) utilizes a networkless environment to
communicate with the server (service provider), we can identify users by
generating a one-time random code, making a robust authentication
environment in cyber security possible.
