```

## Discussion

Discussion The application specific state of the biometric enrollment as returned by @c LAContext.domainState.biometry.stateHash This value represents the state of the enrollment and changes whenever the biometric enrollment is changed. It does not directly map to the enrolled templates, e.g. if a finger is added to Touch ID enrollment and then removed, the final state would be different. It also returns different values to different apps to prevent tracking of user identity.
