Title: Improve Login Page Feedback for Incorrect Credentials

Issue Description:
When a user enters incorrect credentials on the login page, there is currently no feedback from the web server, leaving the user confused about whether the login attempt was successful or not. We need to enhance the user experience by providing a generic error message that suggests something may have happened and then ceased to happen or that something went wrong without explicitly revealing the specific error, such as a password mismatch.

Expected Behavior:

• User receives a feedback message on the login page in case of incorrect credentials.
• The message should be generic, indicating that something may have occurred and then ceased to happen or that an error occurred during the login attempt.

Additional Information:

• Avoid explicitly mentioning the nature of the error to maintain security and prevent potential exploitation.
• Enhancing the user feedback will contribute to a more user-friendly experience and reduce confusion during the login process.

Priority:
Set priority based on the impact on user experience. Consider making this a high-priority improvement to enhance the security and usability of the login page.
