Unblocking Customers in Magento After Too Many Failed Login Attempts

Magento provides robust security features to protect customer accounts from unauthorized access. One of these features is temporarily blocking customer accounts after a certain number of failed login attempts. While this helps enhance security, it can also result in genuine customers being blocked from accessing their accounts. This article explains why this happens and how to unblock a customer by checking the oauth_token_request_log table.

Why Customers Get Blocked

When a customer tries to log in to their account, Magento checks the credentials against its database. If the customer enters incorrect credentials multiple times, Magento temporarily blocks further login attempts for that customer to prevent brute force attacks. This mechanism is designed to protect customer data and ensure account security.

The number of failed login attempts before a customer gets blocked can be configured in Magento's admin settings under Stores > Configuration > Customers > Customer Configuration > Password Options.

Unblocking a Customer

To unblock a customer who has been blocked due to too many failed login attempts, you need to clear the failed login attempts logged in the oauth_token_request_log table. This table logs all the OAuth token requests, including failed login attempts. Follow these steps to unblock a customer:

Step 1: Access the Database

First, access your Magento database using a database management tool like phpMyAdmin or a command-line interface like MySQL.

Step 2: Identify the Customer

Identify the customer who needs to be unblocked. You will need the customer's email or customer ID.

Step 3: Query the oauth_token_request_log Table

Run the following SQL query to find the failed login attempts for the customer:

SELECT * FROM oauth_token_request_log WHERE user_id = (SELECT entity_id FROM customer_entity WHERE email = '[email protected]');

Replace [email protected] with the customer's actual email address. This query retrieves all token request logs for the specified customer.

Step 4: Delete Failed Login Attempts

To unblock the customer, delete the relevant rows from the oauth_token_request_log table:

DELETE FROM oauth_token_request_log WHERE user_id = (SELECT entity_id FROM customer_entity WHERE email = '[email protected]');

This query removes all token request logs for the specified customer, effectively resetting their failed login attempts.

Step 5: Inform the Customer

Once you have cleared the failed login attempts, inform the customer that they can now try logging in again.

Conclusion

Blocking customers after too many failed login attempts is a critical security measure in Magento. However, genuine customers can sometimes be blocked inadvertently. By checking and clearing the oauth_token_request_log
