To ensure that customers can continue to use our services safely and securely, we plan to implement a security update (major update) for the HENNGE Lock app around December 2026 to January 2027.
This update enhances the way registered one-time password (OTP) key information is securely stored and managed within the app. There is no need to update the app immediately; however, as this is an important Notice regarding a future update, we are informing you in advance.
By updating your app to the latest version, the above update will also be applied automatically.
No action is required other than updating the app.
However, as this enhancement is a major update, we recommend that you consider taking precautions, such as creating a backup (export), in advance.
