The script `extract_otp_secrets.py` is designed to extract one-time password (OTP) secrets from QR codes generated by two-factor authentication apps like Google Authenticator. It supports multiple methods of reading QR codes, including via camera, image files, and text files, with output options for JSON, CSV, or printed QR codes. The project consolidates functionalities into a single executable, requiring no installation of Python or dependencies, but warns users about potential antivirus false positives.
