AWS Cognito authentication without password for backend server-server call

Question

We have started to explore AWS Cognito for authentication with our applications. Right now, we developed a POC application where user signs up/sign in with a password and obtains the JWT. But from server-server we need to a way to login and obtain the JWT without a password(like a trusted sign in ).But when I explored, I found an article https://aws.amazon.com/blogs/mobile/implementing-passwordless-email-authentication-with-amazon-cognito/. But in this article, still there is an otp sent to client. We don't want to interact with the client in server-server communication.Is there any feature that AWS cognito offers for the above requirement.

Answer 1

We use a model like the one described in this article.
