Lockout Metamask: « Not connected to » Error when using the standard authentication flow
The tokens (NFT) continue to grow, however, a common problem that arises when the use of standard authentication flows on metamask is obtained «
.
The problem: standard authentication flow
When users connect to their Metamask account via traditional authentication flow (for example, username and password), they are redirected to the Metamask connection page. On this page, they enter their identification information (username and password) and submit it. The wallet is unlocked, allowing access to the blockchain.
However, what they are precisely where the « unconnected » error occurs: due to incorrect authentication, Metamask does not recognize that the user is already connected.
Causes of the problem
Several factors contribute to this question:
1 and 1
- Authentication flow without security :
.
Solution
Use:
1 and 1
2
- Improve the authentication flow
: Consideration and more secure authentication flow, such as provides more advanced protection against phishing attacks.
Example of improved authentication flow
Here is an updated code extract which demonstrates a more secure authentication flow:
`Javascript
Import {Ethers} of 'Ethers';
Import {Connectwallet} from './connectwallet';
Constructwalletenhanced = async () => {
// Configures the web3 supplier with webauthn or weth
Const web3Provider = New Ethers.Providers.Web3Provider (Window.ethereum);
to try {
// Connect to the Ethereum network using an improved authentication flow
Const Provider = wait web3Provider.Connect (Name: 'Your-App-Name'});
Return supplier;
} Catch (error) {
Console.error (error);
}
};
Constwalletfromereum = async () => {
Const {account, supplier} = Connectwalletenhanced ();
// Use the wallet to interact with blockchain applications
};
` ‘
2FA and 2FA, you can considerably risk metamasque to be « locked »
