# Biometric Bypass Feature for Real Devices

## 1. Introduction

The Biometric Bypass feature offers a streamlined way to bypass biometric authentication prompts, such as fingerprint or facial recognition, during testing on real iOS and Android devices. This feature is especially useful for testing scenarios where manual biometric interactions might hinder efficient testing.

### Benefits of using Biometric Bypass

* **Efficiency**: Biometric Bypass speeds up testing by eliminating the need to manually interact with biometric prompts.
* **Repetitive Testing**: In scenarios requiring repeated testing, bypassing biometric prompts prevents unnecessary delays.
* **Testing Various Scenarios**: Biometric Bypass lets you focus on testing core functionality without being hindered by authentication prompts.

## 2. Accessing Biometric Bypass

To use the `Biometric Bypass` feature toggle the Biometric flag while starting a session after selecting the application. ![Biometrics Session Start](/files/kxBfDEwsFpZ5OURKOs6C)\
The session then starts with biometrics bypass enabled for that app.

```
Note: Biometric feature may not work on iOS 17+
```

> **Note:** Biometrics bypass is supported on selected devices and works on instrumentable debug build only.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.qyrus.com/device-farm/biometrics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
