Code examples

Prerequisites

For prerequisites, see the README in the dotnetv3 folder.

These examples also require the following resources:

• An existing Amazon Cognito user pool that is configured to allow self sign-up.
• A client ID to use for authenticating with Amazon Cognito.

To create these resources, run the AWS CloudFormation script in the resources/cdk/cognito_scenario_user_pool_with_mfa folder. This script outputs a user pool ID and a client ID that you can use to run the scenario.

Run the examples

Instructions

For general instructions to run the examples, see the README in the dotnetv3 folder.

Some projects might include a settings.json file. Before compiling the project, you can change these values to match your own account and resources. Alternatively, add a settings.local.json file with your local settings, which will be loaded automatically when the application runs.

After the example compiles, you can run it from the command line. To do so, navigate to the folder that contains the .csproj file and run the following command:

dotnet run

Alternatively, you can run the example from within your IDE.

Sign up a user with a user pool that requires MFA

This example shows you how to do the following:

• Sign up and confirm a user with a username, password, and email address.
• Set up multi-factor authentication by associating an MFA application with the user.
• Sign in by using a password and an MFA code.

Tests

⚠ Running tests might result in charges to your AWS account.

To find instructions for running these tests, see the README in the dotnetv3 folder.
