Yes. On an eligible iPhone, use Apple’s built-in app lock on the Lockin Smart app. Touch and hold the Lockin Smart icon, tap Require Face ID (or Touch ID or Passcode), and authenticate. The next time you open the app, iPhone asks for authentication before the app’s controls appear.
This protects access to Lockin Smart on that iPhone. It is an iPhone operating-system control, not a new Lockin lock setting and not a Face ID confirmation at the deadbolt itself.
What this protects
Lockin’s Veno Pro documentation lists app control and mobile-app remote unlocking. Its manual describes the normal owner workflow as opening Lockin Smart and pressing and holding Unlock, with Wi-Fi remaining connected. Locking the app adds a phone-level checkpoint before someone can reach that workflow on the protected iPhone.
That is useful when another person can pick up or borrow the owner’s unlocked phone. It can help prevent an accidental or unauthorized trip into the Lockin Smart app, while leaving the lock’s supported entry methods available to authorized household members.
Set up Face ID for the Lockin Smart app
- Install and sign in to the current Lockin Smart app, and confirm that you can complete the normal owner workflow before changing the protection.
- Go to the iPhone Home Screen.
- Touch and hold the Lockin Smart app icon until its quick-actions menu appears.
- Tap Require Face ID. Depending on the iPhone, the wording may instead offer Require Touch ID or Require Passcode.
- Authenticate when prompted.
- Close the menu, then tap Lockin Smart again. Confirm that the iPhone requests authentication before the app opens.
- After authentication, check that the correct lock and the normal controls are available. If you intend to use remote unlock, test the owner workflow without actually unlocking the door unless you are in a safe position to do so.
Apple says a locked app relocks after you quit it. Reopen it after quitting to confirm that the prompt returns. Do not treat the first successful authentication as a permanent unlock of the app.
What happens to notifications?
Apple says information inside a locked app does not appear in places such as notification previews, search, Siri suggestions, CarPlay, or call history. That can improve privacy, but it can also change how quickly you understand a Lockin doorbell or activity alert from the Lock Screen.
After enabling the app lock, send or wait for a normal Lockin notification and decide whether the new preview behavior still works for your household. Open the notification only after authenticating, and use the Lockin app’s Events or live-view workflow when you need the full context. Do not assume that hiding a preview turns alerts off or changes what the lock records.
Should you turn on Stolen Device Protection too?
It is an optional extra layer for the iPhone, not a Lockin feature. Apple says that when Stolen Device Protection is on, a locked app requires Face ID or Touch ID away from familiar locations, with no passcode fallback for that situation. The ordinary locked-app setting can allow Face ID, Touch ID, or the device passcode.
If you enable Stolen Device Protection, test your real owner workflow before relying on it away from home. Make sure the person responsible for the Lockin account can authenticate and still has an appropriate way to enter the home if the iPhone, app, network, or biometric check is unavailable.
Important limits
| It does | It does not do |
|---|---|
| Require authentication before Lockin Smart opens on the protected iPhone | Add a Face ID prompt at the Lockin deadbolt |
| Relock the app after you quit it | Revoke another household member’s phone, account access, or credentials |
| Reduce what the locked app reveals in certain iPhone surfaces, including notification previews | Lock Apple Home, Alexa, Google Home, Matter, or another remote-control path automatically |
| Apply locally to that iPhone | Sync its locked status to iCloud or every phone using the same Lockin setup |
It also does not replace a physical key, a supported keypad or biometric method, emergency power procedures, or any other documented way to enter the home. Keep an accessible fallback for the people who need one.
If Require Face ID is missing, do not assume that Lockin has removed the feature or that the Lockin lock supports a native equivalent. Check that the iPhone software and app installation are eligible for Apple’s app-lock control, that you are using the downloaded Lockin Smart app, and that the phone is not restricted by a family, workplace, or device-management policy. If the option remains unavailable, use the Lockin account and device-access controls documented for your exact model and contact support rather than promising an unsupported setting.
A safe verification checklist
- The Lockin Smart icon asks for Face ID, Touch ID, or the passcode after you quit and reopen it.
- The correct Lockin device is still visible after authentication.
- A normal Lockin notification behaves as expected, including the amount of preview detail shown.
- You know which other phones, household users, smart-home apps, and physical credentials can still control or open the lock.
- At least one authorized person has a practical fallback entry method.
- You have not confused app access protection with a test of the door’s actual locked or unlocked state.
For a Veno Pro owner, the Veno Pro product page describes the supported app-control and entry-method context. Use the Lockin user-manual library for the current model documentation, and check the Lockin FAQ when an account, connectivity, or access question remains unresolved.
The practical answer is simple: lock the Lockin Smart app on the iPhone, quit and reopen it to verify the prompt, then test notifications and a safe owner workflow. Just remember what is being protected—the app on that phone—not every way a Lockin smart lock can be controlled or opened.
