# livenessMoveSteps

## Details

**Attribute:** `liveness-move-steps`

**Type:** `number`

**Supported values:** `0` or higher

**Default value:** `0`

## Morphology

```typescript
selphi.livenessMoveSteps = 3;
```

## Description

Number of steps of the active liveness check (liveness move) in `facephi-selphi-widget`. The value `0` disables this mode.

This mode activates a pre-capture phase where the user must follow a series of instructions to prove they are a real person.

The applied value corresponds to the number of instructions the user must successfully complete before the capture phase.

### Additional information

**Recommended property:** use `moveSuccessfulAttempts` in new integrations.

**Precedence:** if you define `livenessMoveSteps` and `moveSuccessfulAttempts` at the same time, `moveSuccessfulAttempts` takes precedence and a precedence warning is emitted in the console.

**Deprecation:** `livenessMoveSteps` is still operational in this version, but it will be removed in the next major version. Use only `livenessMoveSteps` emits a deprecation warning in the console.

**Activation of liveness move:** specifying steps > 0 activates the mode *move* for compatibility, but the recommended way is to define [`livenessMode`](/docs.facephi-en/sdks/sdk-web/componentes/selphi-biometria-facial/propiedades/livenessmode.md) = `LivenessMode.Move`. See [`livenessMode`](/docs.facephi-en/sdks/sdk-web/componentes/selphi-biometria-facial/propiedades/livenessmode.md) for details on mode derivation.
