If the site you mention is a perfect and secure way of recovering bitcoin password it is a good news. I have heard so many people cry because they cannot have access to their wallet due to forgetting password. This will also have disadvantage in the sense that some people may use it to penetrate others wallet. If we value our bitcoin we will use every means to secure and keep our password.
This software can operate without a network so that we can protect our confidentiality, and it doesnt upload any of your information, without giving other people any opportunity to steal your money
