Hello JOHNY thanks for your interest. Sorry I just elaborated upon that first question 7 minutes prior to this question 
could you consult my reply here:
With regards to how Web2 APIs improve the overall security of the asset - they empower users and organizations using our protocol with the ability to use the rich and far more established world of Web2 MFA providers. We have demonstrated this by integrating google and microsoft MFA, but ANY traditionally Web2-only domain such as Pass Keys, FaceID, custom government issued biometrics verification, etc. is now available to our users. Any number and any sequence of MFA providers can be made available via our flexible and extendible protocol in the future.
