Authentication

No Password.
Just Your Wallet.

Wallet-signature login is the most secure authentication method available today. Metahandle makes it as simple as clicking a button.

The Shift

Passwords Are a Broken System

Every year billions of passwords are leaked in data breaches. Phishing attacks steal credentials by mimicking trusted sites. Passwords solve none of these structural problems.

Wallet-based login works differently. Your wallet signs a unique message with its private key. The server verifies the signature without ever seeing your key. There is nothing to steal from their database.

This approach is called Sign-In With Ethereum — SIWE — and similar standards exist on Solana and other chains. Metahandle wraps this into one unified login flow across all networks.

How Wallet Login Works

The process is straightforward and takes less than five seconds for the user.

01

Request

The app sends a unique challenge message to your wallet. This message is time-stamped and tied to the specific login session.

02

Sign

Your wallet asks you to sign the message. Signing proves ownership of the wallet address without revealing your private key.

03

Verify

The server checks the signature and confirms it matches your wallet address. Access is granted — no password database needed.

What Metahandle Adds

Standard SIWE requires users to know which wallet address they registered with. Metahandle removes this friction by linking your readable handle to all your wallet addresses.

You type your metahandle. The system resolves which wallet to use. You sign one message and you are in. It works the same way across every app that supports metahandle authentication.

For developers, integrating metahandle means supporting dozens of wallets and chains with a single API call. Users benefit from a consistent experience no matter which dApp they visit.

Comparison

SIWE vs Password Login

Traditional Password

  • ✗

    Stored on servers — leakable in breaches.

  • ✗

    Phishable via fake login pages.

  • ✗

    Requires one account per service.

Wallet Signature Login

  • ✓

    Private key never leaves your device.

  • ✓

    Signature is session-specific — useless if stolen.

  • ✓

    One wallet serves every app that supports SIWE.
