API Ringkasan

isAvailable

Mengecek apakah perangkat autentikasi biometrik tersedia.

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

await NativeBiometric.isAvailable();

verifyIdentity

Mengajak pengguna untuk melakukan autentikasi dengan biometrik.

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

await NativeBiometric.verifyIdentity();

getCredentials

Mengambil kredit yang disimpan untuk server tertentu.

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

await NativeBiometric.getCredentials({} as GetCredentialOptions);

setCredentials

Menyimpan kredit yang diberikan untuk server tertentu.

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

await NativeBiometric.setCredentials({} as SetCredentialOptions);

deleteCredentials

Menghapus kredit yang disimpan untuk server tertentu.

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

await NativeBiometric.deleteCredentials({} as DeleteCredentialOptions);

getSecureCredentials

Mengambil kreditensi yang disimpan untuk server tertentu, memerlukan verifikasi biometrik. Kreditensi harus telah disimpan dengan accessControl diatur ke BIOMETRY_CURRENT_SET atau BIOMETRY_ANY.

Pada iOS, sistem secara otomatis menampilkan prompt biometrik ketika mengakses item Keychain yang dilindungi. Pada Android, BiometricPrompt ditampilkan dengan CryptoObject terikat pada kunci dekripsi kreditensi.

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

await NativeBiometric.getSecureCredentials({} as GetSecureCredentialsOptions);

isCredentialsSaved

Memeriksa apakah kreditensi sudah disimpan untuk server tertentu.

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

await NativeBiometric.isCredentialsSaved({} as IsCredentialsSavedOptions);
