## Overview

DecNect's Web3 login system provides secure, decentralized authentication that eliminates traditional usernames and passwords. Users authenticate using their Web3 wallets while maintaining complete control over their digital identity and data.

## How It Works

### Authentication Process

1. **Wallet Connection**: Connect Web3 wallet to DecNect
2. **Signature Request**: Platform requests cryptographic signature
3. **Identity Verification**: Signature verified on blockchain
4. **Session Creation**: Secure session created for user
5. **Access Granted**: User gains platform access

### Security Features

* **Cryptographic Signatures**: Advanced signature authentication
* **Nonce Generation**: Prevents replay attacks
* **Session Management**: Secure session handling
* **Token Validation**: On-chain token validation
