How can I use React Native Keychain for secure storage?

You can use the React Native Keychain library to securely store sensitive data like passwords and tokens. First, install the library using npm or yarn.

What are the basic methods available in React Native Keychain?

The main methods include setGenericPassword, getGenericPassword, and resetGenericPassword. These allow you to store, retrieve, and delete credentials.

Can you show me a code example for storing a password?

Sure! Here's a simple example:

import * as Keychain from 'react-native-keychain';

async function storePassword(username, password) {
  await Keychain.setGenericPassword(username, password);
}

How do I retrieve the stored password?

You can retrieve it using the getGenericPassword method like this:

const credentials = await Keychain.getGenericPassword();
if (credentials) {
  console.log('Credentials successfully loaded for user ' + credentials.username);
} else {
  console.log('No credentials stored');
}
