Two-Factor Authentication on Android

The upcoming version 3.8 of the Nextcloud Android app will support Two-Factor Authentication out-of-the-box using the Hardware Security SDK. With just 18 lines of code, the app now supports FIDO authentication by extending the WebView that has already been used for the login flow.

Exceet Connect

Security Solutions for the Industrial Internet of Things (IIoT)

Our partner Exceet Secure Solutions is working with mechanical engineering companies to connect their industrial plants to a IIoT. Since plants are often critical infrastructures, their security requirements are high. To fulfill at least level 2 of the industry standard IEC 62443, physically separated key storages are required.

The Hardware Security SDK has been integrated in their IIoT administration app to use smartcards over NFC for authentication. This allows non-IT personal to configure their industrial plants in a secure and convenient way.

Tungsten Messenger

Secure Messenger with Full App Encryption

Tungsten is an end-to-end encrypted messenger that allows each user to have two types of personas: public and anonymous. While the public persona is connected to your mobile phone number, the anonymous one is ephemeral and routed over Tor for anonymization.

In collaboration with Tungsten Labs, we released the Tungsten Key to fully encrypt and hide their anonymous personas over NFC. This means that anonymous chats cannot be accessed even when the phone is confiscated or stolen.
