I have a situation where i need to integrate my Gateway before my end application in order to restrict the user access. So the flow of request will be like:
Client with username and password ----> Gateway --> My end application.
My question is : If users are external, then Is it possible that whenever a new user wants to access my application, we can generate an OTP (or anything related to this) for login of the user into the gateway. If any other way is there that also please let me know.
