Metamask Lock: “unsigned” errors using standard authentication flow
As decentralized funding (DEFI) and the popularity of non -fungal chips (NFT) continues to increase, web3 money exchange, such as Metamk, has become essential components to interact with blockchain applications. A common problem arising from the standard authentication current metamk is that they are “locked” or not registered due to incorrect passwords.
In this article, we will check the causes of this problem and provide a solution to the solution.
Problem: Standard Authentication Flow
If users log in to their Metamask account using the usual authentication flow (such as username and password), they are diverted to the Metamask registration sheet. Enter the login information (user name and password) on this page and send. If the login information corresponds to the user’s existing Metamask wallet settings, the wallet is unlocked so that access to the blockchain is possible.
However, what happens if the attacker tries to intercept or manipulate the field and password? You can create a false Metamk account with exactly the same login information as the actual user and you may not be able to free access to the wallet. This is where the mistakes seem “not registered”: due to incorrect authentication, Metamk does not recognize that the user is already registered.
Causes of Problem
Several factors contribute to this topic:
1
weak passwords : If the passwords are too weak or easily guessed, the attacker can hack them and access the wallet.
- A troubled authentication flow : The usual registration flow Metamk may not be safe enough to prevent unauthorized access.
3
Between the site counterfeiting (CSRF)
: If the malicious site threatens the metamast’s authentication flow, the attacker may be able to make the user specify his / her password.
Solution
To prevent this problem and ensure safe use of Metamass:
- Introduce two -factor authentication (2fa) : Activate 2FA to add an additional security level to your account.
- Use a powerful password
: Make sure your Metamask password is strong, clear and not easy to guess.
3
Update the authentication flow : Consider the implementation of safer authentication flow, eg.
Example of expanded authentication flow
Here is an updated code passage that shows a safer authentication flow:
`JavaScript
Import {ethers} from ‘ether’;
Import {Connectwallet} from ‘./Connectwallet’;
Connectwalletenhanced = async () => {
// Set a Web3 service provider with Web Authte or OAUTH
Const Web3Provider = New Ether.providers.Web3Provider (Window.ethereum);
attempt {
// Using an extended authentication flow with an Ethereum network, connect to the Ethereum network
Const Provider = Waiting Web3Provider.connect ({NAME: ‘Your-APP NAME’});
Return service provider;
} Catch (error) {
Console.Error (error);
}
};
Const TwalletFrometereum = Async () => {
Const {account, service provider} = Connectwalletehanced ();
// Use a wallet to interact with blockchain applications
};
`
By introducing a safer authentication flows and the use of strong passwords and 2fa, you can significantly reduce the risk of Metamk registered using standard authentication currents.
