React Native Auth0 Plus

Added missing functions of react-native-auth0 for full native authentication flow.

For example, there is no API of react-native-auth0 to handle mfa_required error during MFA Login. This library provides APIs to:

1. Query user's existing authenticators (e.g. sms, one-time-password, etc...).
2. If authenticators exist, challenge users with their registered authenticators (e.g. send sms code to user's phone).
3. Otherwise, associate specific authenticator (e.g. sms, email, etc...) with users.

This is an unofficial library, all its features should be considered as alternatives. Developers should always check if latest official library (react-native-auth0) has implemented the same features before using this library.

Usages

import {
    default as Auth0Plus,
    AuthenticatorType,
    OobChannel
} from 'react-native-auth0-plus';

const helper = new Auth0Plus('<client-id>', '<domain>');

For brevity, the rest of the examples will leave out the import and/or instantiation step.

Query user's existing authenticators

Query sms authenticators ONLY

const [{ id: smsAuthenticatorId }] = await helper.queryAuthenticators({
    mfa_token,
    oob_channel: OobChannel.sms,
    authenticator_type: AuthenticatorType.oob
});

Query all authenticators

const allAuthenticators = await helper.queryAuthenticators({
    mfa_token
});

Associate users with their phone number or email

After querying user's authenticators and find that user has not associated with specific authenticators. Your app prompts users to input phone numbers or email addresses, sends request to associate with these peronal information and get response of OOB Code.

// sms
const { oob_code, recovery_codes, ...} = await helper.associatePhone({ mfa_token, phone_number });

// email
const { oob_code, recovery_codes, ...} = await helper.associateEmail({ mfa_token, email });

// General request
const { oob_code, recovery_codes, ...} = await helper.associate({ ... })

Challenge users

After querying user's authenticators and find that user has associated with some authenticators (got authenticator id), Your app challenge these authenticators by using react-native-auth0.multifactorChallenge(...) or shortcut of this library.

const oobCode = await helper.challengeOob({
    authenticator_id,
    mfa_token,
})

The oobCode is required for next login flow.
