API Panoramica

isAvailable

Verifica se sono disponibili dispositivi di autenticazione biometrica.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.isAvailable();

verifyIdentity

Sollecita l'utente a autenticarsi con i biometri.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.verifyIdentity();

getCredentials

Ottiene le credenziali memorizzate per un server specifico.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

Memorizza le credenziali fornite per un server specifico.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.setCredentials({} as SetCredentialOptions);

deleteCredentials

Cancella le credenziali memorizzate per un server specifico.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.deleteCredentials({} as DeleteCredentialOptions);

getSecureCredentials

Ottiene le credenziali memorizzate per un server specifico, richiedendo l'autenticazione biometrica. Le credenziali devono essere state memorizzate con accessControl impostato su BIOMETRY_CURRENT_SET o BIOMETRY_ANY.

Sul sistema iOS, il sistema mostra automaticamente la finestra di dialogo per l'autenticazione biometrica quando si accede all'elemento Keychain protetto. Sul sistema Android, viene mostrata la finestra di dialogo BiometricPrompt con un oggetto CryptoObject legato alla chiave di decrittazione delle credenziali.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

Verifica se le credenziali sono già salvate per un server specifico.

import { NativeBiometric } from '@capgo/capacitor-native-biometric';

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
