## Installation

```sh

npm install capacitor-face-id

```

## iOS Notes

iOS requires the following usage description be added and filled out for your app in `Info.plist`:

Name: `Privacy - Face ID Usage Description`




Key: `NSFaceIDUsageDescription`

## Example

```ts

import { Plugins, PluginResultError } from '@capacitor/core';

const { FaceId } = Plugins;

...

// check if device supports Face ID or Touch ID

FaceId.isAvailable().then(checkResult => {

  if(checkResult.value) {

    FaceId.auth().then(() => {

      console.log('authenticated');

    }).catch((error: PluginResultError) => {

      // handle rejection errors

      console.error(error.message);

    });

  } else {

    // use custom fallback authentication here

  }

});

```
