@SDFC - Great effort behind making the video. Thanks. I really liked how you did capacity planning for cache memory. I have a some thoughts on the design. I would not integrate authentication and authorisation within the OTP sub system so that the OTP system can be used by any system that needs a 2FA. Apart from storing the OTP in cache, I would also maintain some more attributes in order to generate MIS reports(in case the OTP is sent as a text message using the SMS which costs money) and also for rate limiting.
