How can I handle user authentication errors in Flask-Security?

You can handle authentication errors in Flask-Security by customizing the error messages and using the @auth.error_handler decorator.

Can you show me an example of customizing error messages?

Sure! You can define a custom error handler like this:

@auth.error_handler
def handle_auth_error():
    return jsonify({'error': 'Authentication failed!'}), 401

What if I want to log these errors for debugging?

You can log errors by using Python's logging module. Just add a logging statement in your error handler.

Thanks! Is there a way to redirect users after a failed login?

Yes, you can use Flask's redirect function to send users to a specific page after a failed login attempt.
