2. Enter your current PIN.

{% hint style="info" %}

{% hint style="info" %}
**Note:** Remember your new PIN! If you forget it, you will need to delete the key and register it again.
{% endhint %}

{% hint style="warning" %}
**Restrictions:**

* You have **10 attempts** to enter your PIN.
* After **5 unsuccessful attempts**, each subsequent attempt can only be made after **3 minutes**.
* If you enter the wrong PIN 5 more times after that, all data in the app will be erased, and you will no longer be able to use your accounts for authentication.
  {% endhint %}

## Enable Biometric Authentication

You can enable biometric authentication alongside your PIN to access your authentication accounts.

1. Open the **"Profile"** section.
2. Enable biometrics by toggling the switch.
3. Scan your fingerprint using the fingerprint scanner.

Once enabled, biometrics can be used to log in to the app without entering your PIN.

{% hint style="info" %}
**Note:** You can disable biometrics and use only your PIN. However, this **reduces security**, and we do not recommend it.
{% endhint %}

* **English**
