Treat them as separate layers. Your Lockin Smart App account manages the lock and its Lockin-specific settings; an Apple Home, Google Home, Alexa, or SmartThings account manages the lock as a connected device inside that platform. A Matter setup or pairing code is what authorizes the platform connection during setup—it is not your Lockin app password.
That distinction matters when you add a family member, change phones, remove a home-platform user, or troubleshoot a lock that works in one app but not another. For a Lockin Veno smart lock, keep the Lockin account, home-platform account, Matter pairing information, and local entry credentials documented separately.
The four credentials or access layers to keep separate
| Layer | What it is for | Where it is normally managed | What changing it should not automatically change |
|---|---|---|---|
| Lockin Smart App account | Signing in to the Lockin service and managing the lock’s full setup, settings, access, alerts, and model-specific controls | Lockin Smart App | Your Apple, Google, Alexa, or SmartThings account |
| Home-platform account | Placing the lock in a home, room, household, or automation system | Apple Home, Google Home, Alexa, or SmartThings | Your Lockin account and the lock’s local PIN, biometric, or key access |
| Matter setup or pairing code | Authorizing an already-configured Matter accessory to join another compatible Matter app or ecosystem | The Lockin app and the receiving home app during commissioning | The Lockin app login password |
| Local lock credentials | Opening the door at the lock, such as a PIN, enrolled biometric, or mechanical key when supported by the model | Lockin Smart App and the lock itself | Membership in a home-platform household |
The exact options vary by model and platform. Lockin’s Veno Solar Face page, for example, lists app control, PIN, mechanical key, and voice control, and says that full lock setup, settings, and management belong in the Lockin Smart App. It also says that Alexa and Google Home can connect directly while Apple Home and SmartThings require a compatible Matter device. Treat those as product and platform conditions—not as interchangeable accounts.
What the Lockin app account controls
Use the Lockin Smart App account for the lock’s native ownership and administration tasks. Depending on the model, that includes adding the device, completing Bluetooth and Wi-Fi setup, managing access, configuring the lock, reviewing activity, and applying model-specific settings. Lockin’s FAQ directs owners to the app’s device settings and Manage Access area to add or remove passwords, fingerprints, and palm-vein data.
If a family member needs native Lockin management, use the Lockin app’s supported household or device-sharing flow when available. Do not hand over the administrator’s password simply because another person needs to use the door. Lockin also states in its FAQ that multiple device logins to the same account are not allowed, so do not assume that sharing one login is the supported way to put the same lock on two phones.
Before changing the Lockin account, confirm that an authorized person still has a working way into the home. A local PIN, enrolled biometric, or mechanical key can be a useful fallback, but the available methods depend on the model and its setup. Never delete the device or factory-reset it merely because a home-platform connection is missing.
What the home-platform account controls
The home-platform account controls the lock’s place in that ecosystem: the home or location, household members, rooms, scenes, automations, and platform-specific permissions. It does not replace the Lockin app account.
For example, removing a resident from Apple Home changes that person’s Home permissions; it does not necessarily remove their Lockin app membership or erase a PIN already stored on the lock. Conversely, changing a Lockin PIN does not automatically remove someone from the Google Home household. Make the change in the system that owns the access you intend to revoke, then verify the other systems separately.
Platform features are not identical. Lockin warns that smart-home features and automations may vary by platform and directs owners to the Lockin Smart App for full lock setup, settings, and management. A home app may expose only the Matter functions that its ecosystem and the specific lock support.
What a Matter code means
A Matter setup or pairing code is a commissioning credential for connecting a compatible accessory to a Matter ecosystem. It is not the email address, password, or recovery credential for your Lockin Smart App account, Apple Account, Google Account, Amazon account, or Samsung account.
If the lock is already paired with the Lockin app, adding it to another compatible Matter app is a separate multi-admin step. Apple’s current Matter guidance says to choose the previously paired accessory path in Home; Google’s guidance similarly describes sharing a Matter device from a manufacturer app or using Matter multi-admin. Follow the current Lockin app and receiving-platform instructions for generating or entering the code. Keep a newly generated code private and use it only in the intended home.
Do not copy the Lockin app password into a Matter setup-code field, and do not treat a setup code as a permanent household password. If the second platform fails, first check whether the lock still works in the Lockin app. A platform pairing problem is not proof that the native Lockin account or local entry credentials are broken.
A safe separation checklist
Use this checklist before changing accounts or removing a connection:
- Name the access you are changing. Is it Lockin app administration, a home-platform household role, a Matter connection, or a local PIN/biometric/key?
- Record the current owner or administrator. Confirm which account should remain able to manage the lock after the change.
- Keep a local fallback. Test an available PIN, enrolled biometric, or mechanical key before removing app or platform access.
- Change one layer at a time. Remove a home-platform member in that platform; remove a Lockin app member in Lockin; delete a local credential in Lockin’s Manage Access area.
- Test the intended result. Check the Lockin app, the home platform, and physical entry separately. A successful sign-in does not prove that the door can unlock, and a working local PIN does not prove that remote platform control remains.
- Document the model and platform conditions. Matter controller, Thread, Wi-Fi, permissions, and available actions can vary by model, platform, software version, and home setup.
If access is not behaving as expected
If the Lockin app works but the home platform does not, check the platform’s device, home, and controller requirements and use the current Matter re-sharing flow. If the home platform shows the lock but a family member cannot control it, check that person’s platform role and the actions exposed for the device. If neither app works, check power, network status, and the Lockin app’s device information before changing credentials.
For model-specific steps, start with the Lockin product page, then check the Lockin FAQ and Lockin user-manual library. Keep the Lockin account and home-platform account recoverable, but do not store passwords or Matter setup codes in a shared note.
The practical rule is simple: use the Lockin Smart App to administer the lock, use the home-platform account to administer its ecosystem membership, use a Matter code only to authorize the supported connection, and manage local entry credentials as their own access layer.
