# Security

> Biometric 2FA, session management, and account security on Sendovex.

## Biometric 2FA

Sendovex supports biometric authentication as a second factor. Once enrolled, you verify your identity using your device's built-in biometrics each time you open the app on that device.

Supported biometric methods:

* Face ID (iPhone, iPad)
* Touch ID (Mac, iPhone)
* Windows Hello (Windows computers)
* Android fingerprint and face unlock

### Enrolling biometrics

1. Tap **Account** at the bottom of the app.
2. Under the **Security** section, tap **Biometric 2FA**.
3. Follow the device prompt to register your fingerprint or face.

### Removing biometrics

Tap **Biometric 2FA** in the same Security section and toggle it off. You will be asked to confirm with your current biometric first.

<Note>
  Biometric credentials are device-specific. If you switch devices or clear your browser data, you will need to re-enroll. Your account is not affected.
</Note>

## Notifications

To receive alerts for trades, escrow changes, support replies, and messages:

1. Tap **Account** at the bottom of the app.
2. Under the **Preferences** section, tap **Notifications** and enable them.

## Signing out

1. Tap **Account** at the bottom of the app.
2. Scroll to the bottom and tap **Sign Out**.

Your session is invalidated. You will need to sign in again. If you have biometric 2FA enrolled on your device, you will be prompted to verify your identity on the next login.

## What Sendovex will never ask

Sendovex support will **never** ask you for:

* Your private key or seed phrase
* Your account password
* A transfer of funds to a safe wallet

If you receive such a request, it is a scam. Report it immediately via a support ticket.

## Lost access to your account

If you cannot sign in:

* Sign in again with your email. A one-time code will be sent to your inbox.
* Contact support if you believe your account has been compromised.

Sendovex support cannot access or control your wallet regardless of the situation.
