Authentication artefacts	JWTs, HTTP basic-auth strings, OAuth bearer tokens, webhook signing secrets	Detectors parse headers and base64 payloads to catch embedded credentials.
Generic API keys	High-entropy keys that do not match a known provider but behave like credentials	Rules combine entropy thresholds with contextual keywords to minimise false positives.
Personally identifiable information	Email addresses, phone numbers, postal addresses, dates of birth, payment cards	PII detections are explained in Confidential Data Detection.
