Device Binding Mode
Last Updated on : 2023-01-31 04:00:03download
Tuya provides multiple device binding modes to meet diversified scenarios and security requirements of smart devices. You can choose a desired binding mode based on your product requirements.
Use case
Take a use case for example: User A has bought a security camera and bound it with Account A, in order to know what is going on in his home. Without User A’s knowledge, User B binds the camera with Account B and can view the live videos from the camera. As a result, User A’s privacy security can hardly be ensured.
In this case, if the camera is set to the strong binding mode, Account B cannot be bound with the camera until Account A is unbound from the camera first. This device binding mode ensures device security.
Binding modes
| Binding mode | Example | Security level |
|---|---|---|
| Weak binding | Suppose a device has been bound with User A, and User B wants to add the device to Account B. In this binding mode, User B can pair the device and add it to Account B without the consent of User A. | Low |
| Medium binding | Suppose a device has been bound with User A, and User B wants to add the device to Account B. In this binding mode, User B can pair the device and add it to Account B without the consent of User A. On the basis of weak binding, the medium binding mode offers notifications of device unbinding. Therefore, User A can receive a notification on the app that the device has been bound with User B. |
Medium |
| Strong binding | Suppose a device has been bound with User A, then User B wants to add the device to account B. User B must ask User A to unbind or remove the device from Account A before User B can add the device to Account B. | High |
Strong binding can fully guarantee the security of devices. The only inconvenience is that when customers ask for a repair, replacement, or refund, the device must first be unbound from the previous account. For more information about how to unbind devices in bulk, see Unbind Smart Devices.
