Options for the integration

With the SecSign ID SDK you can customize the authentication procedure to best fit your and your customers requirements. You are not sure which integration you want or you have specific requirements? Contact us for a solution that not only works for you but covers all bases for the most convenient setup.

For any setup the authentication is based on a challenge response authentication in the background. The user doesn’t even realize his login is protected with a two-factor authentication because the private key secured on his mobile phone acts as the second factor.
More information about the SecSign ID challenge-response authentication and how the private key is secured can be found on our two-factor authentication basics overview.

Inline Integration

With the inline integration your users are directed to the SecSign ID authentication within your own app. That means you have one app for all user actions, from mobile login to secure mobile authentication and secure authentication for customers using the web login. You can brand the authentication based on your vision and company design to provide your users with their trusted banking environment. All banking actions, authentication and login are located in the same app with no external actions required. The user only needs to download one app for all banking, login and authentication actions.

Call-to-Authentication Integration

The call-to-authenticate integration integrates the two-factor authentication option in your app, and opens a customized two-factor authentication app for the authentication procedure itself. The two-factor authentication app can be branded to fit your vision and company design. The switch to the authentication app and the switch back to the banking app are fully automatic with no user input required beyond the authentication itself. Once the user successfully authenticated he is automatically returned to the banking app to continue with his banking activities.

With this option you can react to any OS, app and security updates and patches without adjusting your based app. It also makes logging for bugs easier for you.
