MingKi Locker is a new way to protect your content with passcode on home screen widgets. By leveraging interactive features of widgets, you can now unlock your content on the widget without opening the app. Passcode You can set a 6-digit passcode for each locker. There is no way to retrieve a passcode because it is encrypted and stored in a local device. Face ID is used to reset passcode. Rich Content Each locker can contain text, photos, audios, recordings and drawings. Each locker supports transparent and gradient background. Widget can be hidden when transparent background is used. Upload & Share Once you complete your locker creation, you can upload your locker and share the code with your audience. Join Lockers You can invite others to join your locker by sending code or QR Code. Others just simply input the code to join. Version Update When you update a new version of your locker, your audience can get the update by reloading the locker. Reload frequency can be easily changed.
