However, there are scenarios where you might want to send a plain registration notification email without any verification links or tokens. This post will walk you through the process of achieving this in an ASP.NET Core Web API environment. Understanding Your Current Setup You're already using Microsoft.AspNetCore.Identity to handle user registration in your application. By default, this setup includes a mechanism for email confirmation. However, since your requirement is to disable email verification and instead provide the user their credentials directly, you'll need a few adjustments in your current implementation of the email service and the registration process. Current Email Sending Process Your MailService is well-structured and capable of sending emails using the MailKit library. Here's a brief overview of how it's set up: MailService Class: This class is responsible for composing and sending emails. MailRequest Class: It serves as a DTO (Data Transfer Object) to hold necessary information like the recipient's email, subject, and body of the email. GetEmailBody Function: This helper method constructs the email body using a template. Your Objective Cut out the part where the user must confirm their account through a link and directly send them their username and password in the body of the email. Step-by-Step Solution Here's how to modify your current code to send a registration email containing the username and password: Step 1: Disable Email Confirmation Requirement You need to configure the identity options to skip the email verification process.

Step 2: Constructing the Email Body You already have access to the user's username and password at the time of registration. You can directly fetch this information from the model. Modify your registration method as follows: Obtain the username from the mapped user object. Include the password in the email body. Here’s how you would integrate these changes: [[See Video to Reveal this Text or Code Snippet]] Important Considerations Security Warning: Sending plain text passwords in emails can pose a security risk. It's highly recommended to implement strategies like password resets or using temporary passwords rather than sending them outright. Customization: You can further customize the email body to include other helpful information such as support contact details or links to help articles. Conclusion In this guide, we explored how to send a registration notification email that includes direct login details to users without requiring an email verification link. By adjusting the identity services and modifying the email composition, this method allows users to access their new accounts quickly. Always consider user experience and security when implementing such features in your applications. By following these steps, you can enhance your ASP.NET Core Web API experience and tailor user engagement directly from the registration point!
