Mapping Generator (edit)

MappingGenerator was initially created as a design-time alternative to AutoMapper. Now it is evolving into a coding assistant to whom you can delegate the most mundane coding tasks.

Versatile OpenID Connect stack for ASP.NET Core 2.1/3.1/5.0 and Microsoft.Owin 4.2 (compatible with ASP.NET 4.6.1)

OpenIddict aims at providing a simple and easy-to-use solution to implement an OpenID Connect server in any ASP.NET Core 1.x or 2.x application. OpenIddict is based on AspNet.Security.OpenIdConnect.Server (codenamed ASOS) to control the OpenID Connect authentication flow and can be used with any membership stack, including ASP.NET Core Identity.

ASP.NET Core and MongoDB (edit)

Cloud: AWS

Configuring the AWS SDK for .NET with .NET Core - AWS SDK for .NET (version 3) (amazon.com)

NuGet Packages:

+ AWSSDK.S3 (Amazon Simple Storage Service (Amazon S3), provides developers and IT teams with secure, durable, highly-scalable object storage.)

+ AWSSDK.Extensions.NETCore.Setup (Extensions for the AWS SDK for .NET to integrate with .NET Core configuration and dependency injection frameworks.)

+ AWSSDK.DynamoDBv2 (Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale.)

+ AWSSDK.CognitoIdentity (Amazon Cognito is a service that makes it easy to save user data, such as app preferences or game state, in the AWS Cloud without writing any backend code or managing any infrastructure. With Amazon Cognito, you can focus on creating great app experiences instead of having to worry about building and managing a backend solution to handle identity management, network state, storage, and sync.)

Amazon Cognito: User Identity Management

Successful web or mobile applications can reach millions of users, and it is critical that such applications have a robust and scalable approach for user and identity management.

Applications can have specific requirements, such as using their own identity store, or leveraging an existing identity provider such as Facebook, Google, or Amazon. Some need to use a combination of their own identity store with existing identity providers. This is often coupled with requirements for a user interface that handles user registration, login, user verification, and forgotten passwords.

Amazon Cognito enables you to add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, including Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0.

Amazon Cognito can also be used to control access to REST APIS through integration with the Amazon API Gateway service, and can reduce the work to authenticate web application users by integrating with
the Application Load Balancer.

Security features include multi-factor authentication, checks for compromised credentials, account takeover protection, and phone and email verification. Amazon Cognito also supports application specific identity stores, user profiles, and customized workflows and user migration through Lambda triggers.
