iOS

keychainService

You can choose the keychain's service which you want to use. Otherwise, the default is app

touchID

Enable TouchID for iOS and fingerprint authentication for Android

SInfo.setItem('key1', 'value1', {  ...  touchID: true,});

kSecAccessControl

When passing in the touchID option as true, you can also set kSecAccessControl. For example:

SInfo.setItem('key1', 'value1', {  keychainService: 'myKeychain',  kSecAccessControl: 'kSecAccessControlTouchIDCurrentSet',  sharedPreferencesName: 'mySharedPrefs',  touchID: true,});

Note: By default kSecAccessControl will get set to kSecAccessControlUserPresence.

kSecAttrSynchronizable

You can set this to true in order to sync the keychain items with iCloud.

Note: By default kSecAttrSynchronizable will get set to false.

kLocalizedFallbackTitle

You can set this to a string and fallback to pin code authentication.

kSecUseOperationPrompt

When touchID is true you must pass kSecUseOperationPrompt to inform users why are you prompting TouchID or FaceID.

Enable Face ID

To enable Face ID, for iOS X and above or iPad Pro, set kSecAccessControl to kSecAccessControlBiometryAny. For example:

SInfo.setItem('key1', 'value1', {  keychainService: 'myKeychain',  kSecAccessControl: 'kSecAccessControlBiometryAny',  ...});
