How Knox Messenger protects your data and privacy
Knox Messenger uses end-to-end encryption to ensure that only you and the intended recipient can read or access your messages and files. End-to-end encryption means that your data is encrypted on your device before it is sent over the network, and decrypted on the recipient's device after it is received. No one else, not even Samsung or third parties, can intercept or decrypt your data in transit or at rest.
Knox Messenger also uses a separate password or biometric authentication (such as fingerprint or face recognition) to access the app. This adds an extra layer of security to prevent unauthorized access to your messages and files if your device is lost or stolen. Additionally, Knox Messenger allows you to set a self-destruct timer for your messages and files, so that they are automatically deleted from both devices after a certain period of time.
