# Activate Face/Iris Login

## Prerequisites

Not all phones support the Class 3 / Strong Biometric Cipher for Face or Iris Authentication.

If you are unsure if your phone supports that feature please ask the manufacturer.

## Let's start

Make sure that you set at least one Face/Iris authentication in your phone's settings to proceed.

From the LockMyPix settings select the option *Fingerprint / Face Unlock*. Select the Face/Iris option and wait a moment for the confirmation.

{% hint style="info" %}
Changing or adding a Face/Iris parameter in your phone's settings requires LockMyPix to reaunthenticate
{% endhint %}

{% hint style="warning" %}
**Important:** Always mind your password even if you login with Face/Iris. Ensure to use the [password recovery](/password/password-recovery.md) to have a fallback
{% endhint %}
