# Wallet PIN

## Definition

A wallet PIN is a short local unlock code used by some wallet applications to make routine device access faster while protecting the app from casual unauthorized use.

## What it means in practice

A PIN is an access-control layer, not blockchain recovery material. It normally cannot recreate wallet keys on another device by itself.

## How this concept appears in Terenval Wallet

Terenval uses a local unlock flow for wallet access. That local credential should be understood separately from seed/recovery material.

**Important:** Choose a PIN that is not trivially guessable and protect the phone itself with device-level security.
