[FEATURE] Implement Credential Verification System

[Hephaestus14089]

Currently, our application does not verify the authenticity of credentials provided by users. This feature request proposes the development of a credential verification system that tests credentials by making a request to the specified website. The system would then analyze the response to confirm the validity of the provided credentials. This would enhance the tool's functionality and security but may require significant development effort and consider potential limitations.
