# Lock the Android app with your fingerprint

Open Settings, then General settings, then Security and Privacy in the XgenPlus app, and tick Enable Finger Print Authentication. Confirm once with your fingerprint. From then on, each time you open the app from the icon, an Unlock XgenPlus prompt appears before your mailbox opens.

## How to lock the Android app with your fingerprint

1. Open **Settings**, then **General settings**, then **Security and Privacy**.
2. Tick **Enable Finger Print Authentication**.
3. Authenticate once. **Fingerprint Enrolled!** confirms it.
4. Next time you open XgenPlus, authenticate at the **Unlock XgenPlus** prompt.

## When to use it

> Priya shares her phone with her family at home. She turns on fingerprint unlock so nobody else can open her office mail.

## Options

| Option | What it does | Default |
|---|---|---|
| **Enable Finger Print Authentication** | Asks for unlock when the app is opened. Applies to the whole app, not each account. | Off |

## Good to know

- On Android 11 and later, your phone's PIN, pattern or password also works at the prompt. On Android 10 and earlier, a fingerprint is needed.
- The prompt appears when you open the app. It is not a timer that locks the app after you leave it.
- Secret Keeper has its own fingerprint setting.

## Common questions

**Why do I not see the option?**

The row is hidden if your phone has no fingerprint or other biometric support.

**What if I cancel the prompt?**

The app shows Unlock cancelled and closes.

**What if no fingerprint is enrolled on my phone?**

The app says no fingerprint is enrolled, turns the setting off and opens normally. Enrol a fingerprint in your phone's settings and switch it on again.
