🔌 API Integration

REST API

Start the API server:

# Enroll user
curl -X POST http://localhost:8080/api/v1/enroll \
  -H "Content-Type: application/json" \
  -d '{"user_id": "john_doe", "password": "secret123"}'

# Authenticate user
curl -X POST http://localhost:8080/api/v1/authenticate \
  -H "Content-Type: application/json" \
  -d '{"user_id": "john_doe", "password": "secret123"}'

# List users
curl http://localhost:8080/api/v1/users

Python SDK

from lockless import LockLessClient

# Initialize client
client = LockLessClient()

# Enroll user
result = client.enroll_user("john_doe", "password123")
print(f"Enrollment: {result.success}")

# Authenticate user
result = client.authenticate_user("john_doe", "password123")
print(f"Authentication: {result.success}")

📚 Documentation

❓ FAQ

General Questions

Q: Is LockLess really 100% offline? A: Yes! All biometric processing happens locally on your device. No data is sent to external servers.

Q: How does it compare to Windows Hello? A: LockLess offers similar functionality with better privacy, cross-platform support, and open-source transparency.

Q: Can I use it on multiple devices? A: Yes, you can enroll the same user on multiple devices. Each device maintains its own encrypted templates.

Q: What if I forget my password? A: You can reset your account by deleting the user and re-enrolling, but this will require re-enrollment.

Technical Questions

Q: What camera resolution is recommended? A: 640x480 or higher works well. The system automatically adjusts quality based on available resolution.

Q: Can I use it without a camera? A: No, LockLess requires a camera for face detection and authentication.

Q: Does it work in low light? A: Yes, but performance may be reduced. Good lighting conditions provide the best results.

Q: Can I customize the authentication thresholds? A: Yes, all thresholds can be adjusted in the configuration file.

Security Questions

Q: How are my biometric data protected? A: All biometric templates are encrypted with AES-256 and stored locally. The encryption key is derived from your password.

Q: Can someone access my biometric data? A: No, without your password, the encrypted templates are useless. The system uses industry-standard encryption.

Q: What happens if my device is compromised? A: Even if someone gains access to your device, they cannot decrypt your biometric templates without your password.

Q: Does LockLess support TPM? A: Yes, on systems with TPM available, LockLess can use it for additional security.

Troubleshooting

Q: Camera not detected? A: Check if other applications are using the camera. Try different camera IDs or update drivers.

Q: Authentication fails frequently? A: Ensure good lighting, clean camera lens, and try re-enrolling with better quality samples.

Q: System runs slowly? A: Check system resources, enable GPU acceleration if available, or reduce image resolution.

Q: GUI doesn't start? A: Ensure PyQt5 is installed and check the logs for specific error messages.

🐛 Troubleshooting

Common Issues

Camera Issues

Camera not detected: Check camera permissions and try different camera IDs
Poor image quality: Ensure good lighting and clean camera lens
Camera access denied: Grant camera permissions to the application

Performance Issues

Slow authentication: Enable GPU acceleration or reduce image resolution
High memory usage: Close other applications or reduce concurrent users
System freezing: Check system resources and update drivers

Authentication Issues

Face not detected: Improve lighting and positioning
Liveness detection fails: Ensure you're not using a photo/video
Biometric match fails: Try re-enrolling with better quality samples
