- Install and Register: Install the app and register a new user account using your cellphone number or email. Agree to the User Agreement and Privacy Policy.

6.1. Adding Fingerprints (Up to 19 total):
The padlock supports up to 19 fingerprints, including 2 administrator fingerprints. To add a fingerprint:
- Open the Smart Life/Tuya App and select your padlock.
- Navigate to "Member Management" or "Settings" and then "Fingerprint".
- Click "Add" to begin the fingerprint registration process.
- Follow the on-screen prompts in the app to place and lift your finger on the padlock's sensor multiple times until registration is complete.
- Name the fingerprint for easy identification (e.g., "Right Thumb").
Note: If the app displays "connecting 10s, connecting 9s" but fails, press the sensor of the lock to wake it up, then try again.
6.2. Unlocking the Padlock:
- By Fingerprint: Place a registered finger firmly on the fingerprint sensor. The LED indicator will turn green, and the padlock will unlock in approximately 0.5 seconds.

6.3. Remote Authorization and Unlocking:
You can authorize other users to unlock your padlock remotely via the app. This requires creating a "home" in the app and adding members.
- Create a Home: In the app, go to "Me" > "Home Management" > "Create a home". Follow the prompts to set up your home information.
- Add Members: Within "Home Management", select your home and click "Add Member". Enter the account details (usually cellphone number) of the person you wish to authorize.
- Accept Invitation: The invited party must download and register the same app. They will receive an invitation which they need to accept.

- Remove Device (Unbind): In the app, select the padlock, go to "Settings" (or device information), and choose "Remove Device" or "Disconnect and wipe data". Confirm the action. After unbinding, the padlock will revert to factory settings, meaning any finger can unlock it until a new administrator fingerprint is registered.
