Description
Biometric login support for GoodixTLS 55x4 devices targets experimental libfprint workflows that may require flashing the fingerprint reader with goodix-fp-dump. It currently focuses on 55b4 support, with related devices expected later.
This is risky hardware-facing authentication work. Flashing a device can break the reader or change its security behavior, so only advanced users with the exact hardware and recovery options should attempt it.
