# Introduction

## Smart wallet built for Harmony

### What is Sef Wallet?

*Sef Wallet* is a smart wallet built for Harmony.  It’s designed to not require passphrase, password, email, or password but instead uses Google Authenticator to recover your wallet.  It’s self custody, private, open-sourced, and security audited.

### Features:

#### Connects with your Harmony’s Dapps & Defi ecosystem

Works with any app that integrates WalletConnect. 

#### Advanced security

Protect your wallet from one device, multiple devices, or ask your friends or family to approve transactions.  Recovery requires 5 consecutive codes from your Google Authenticator (or other OTP app)

#### Built for the future

Upgradable contract without changing smart contract address.
