# Access a Mobile Device’s Biometrics Capabilities

A Lightning web component can use a device’s biometrics functionality to prompt a user to confirm their identity. When these biometrics-related actions occur, the result is returned to the Lightning web component that invoked it.

Biometrics checks are managed locally on the mobile device, and don't need a network connection. However, BiometricsService requires access to platform-specific APIs that are available only within compatible Salesforce mobile apps.

**important:** BiometricsService does not and cannot function when running in a web browser, whether on a desktop or mobile device.

- **[BiometricsService User Experience](https://developer.salesforce.com/docs/platform/mobile-offline/guide/use-biometricsservice-intro.md)**


    Your component can deliver any user experience you desire, but there’s a common flow for any component that calls for a biometrics check.

- **[Use the BiometricsService API](https://developer.salesforce.com/docs/platform/mobile-offline/guide/use-biometricsservice-in-a-lightning-component.md)**


    To develop a Lightning web component with biometrics-checking features, use the BiometricsService API as your method for accessing a device’s native biometrics functionality.

- **[BiometricsService Example](https://developer.salesforce.com/docs/platform/mobile-offline/guide/use-biometricsservice-example.md)**


    Here’s a basic example of a Lightning web component that uses a device’s biometrics capabilities to verify device ownership.

- **[Compatibility and Requirements](https://developer.salesforce.com/docs/platform/mobile-offline/guide/use-biometricsservice-compatibility.md)**


    BiometricsService is a JavaScript module that provides an API to Lightning web components to make mobile hardware and platform (operating system) features available in JavaScript. It **requires** access to device hardware and device platform APIs. This access is only available when BiometricsService runs within a compatible Salesforce mobile app. **It does not and cannot function when running in a standard web browser, whether the browser runs on a desktop or mobile device.**

- **[Considerations and Limitations](https://developer.salesforce.com/docs/platform/mobile-offline/guide/use-biometricsservice-considerations.md)**


    Consider these guidelines and limitations when developing features that use the BiometricsService API.
