The SmartSign App

SmartSign smartphone 2-factor authentication app for secure login to websites and web applications

With the free SmartSign app users can perform two-factor authentication with ease. The app transforms the user's smartphone into a secure and convenient authentication token, providing quick authentication on the go.

You have control over how the user can authenticate, through options set when calling our API or authentication policies created through the Management System.

The SmartSign app supports Out-Of-Band Challenge-Response authentication combined with 2048-bit RSA digital signatures. This authentication procedure ensures non-repudiation and authenticity of response messages.

The app can also generate OTP codes which can be useful as a temporary solution to lost or stolen hardware tokens.
