mobium biometric
This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET
Enroll and present a face or finger (emulators and simulators)
With no argument, says whether a face or finger is enrolled. enroll and unenroll set it: a simulator as its Features menu does; an emulator through Settings, setting PIN 1111 first when it has no screen lock — unenroll removes both. match and nomatch present a matching or a stranger's face or finger to the prompt that is up, and say what the device made of it: accepted, not recognized, or locked out. With no prompt up, nothing is sent. Whether the app signed in is the app's to show. A real phone refuses.
