The integrated semiconductor fingerprint sensor provides quick access.

3.2 Password Unlocking:
The lock supports standard passwords and a privacy password feature.
- Set Passwords: Use the TTLOCK app to create and manage user passwords.
- Privacy Password: To use this feature, enter any random digits before and after your actual password (e.g., [random digits] + [correct password] + [random digits]). This obscures your actual password from potential onlookers.
- Temporary/Normally Open Mode: The app allows setting temporary passwords for guests or a normally open mode for specific periods.
- Auto-Lock Feature: If an incorrect password is entered multiple times, the lock will automatically engage a temporary lockout period for security.
