Mobile SDK Reference

Mobile SDKs


Keyri's mobile SDKs handle the secure cryptographic key generation, key storage, encryption, API communications, desktop session identification, session management, and QR scanning required to make a QR authentication system work.

The SDKs include pre-built QR authentication UIs that you can use to finish the mobile side of the system quickly. This pre-built UI can be customized to match your app's aesthetic. Alternatively, you can call the SDK's lower-level functions to build your own entirely custom QR authentication UI/UX.

Our SDKs and API allow your customers to scan your QR code from anywhere - from within your app or with their phone's built-in camera app. The latter case is handled by App Links (Android) and Universal Links (iOS). The mobile SDK documentation here will walk you through how to set this up.

Keyri's mobile SDKs allow you to send custom data from your app to any client showing the Keyri QR widget, with end-to-end encryption, allowing you to build features that go beyond QR authentication functionality.

Device Fingerprinting

Keyri's mobile SDKs handle the identification of relevant mobile parameters, secure cryptographic key generation, key storage, encryption, and API communications required to create a persistent mobile device fingerprint to track and identify your customers' mobile devices.
