.NET Core provides a variety of [authentication](https://www.mindstick.com/blog/177/authentication-and-authorization-in-asp-dot-net) and authorization [options](https://www.mindstick.com/articles/43878/making-the-best-use-of-the-options-trade-ideas) to help you secure your web applications.

## Authentication

Authentication is the process of identifying a user and verifying their identity. .NET Core supports a number of authentication schemes, including:

- **Basic authentication:** Users enter a username and password to authenticate.
- **Forms authentication:** Users enter a username and password on a login form.
- **OAuth 2.0:** Users authenticate with an external identity provider, such as Google or Facebook.
- **JWT bearer tokens:** Users authenticate with a JSON Web Token (JWT) that is signed by your application.

## Authorization

Authorization is the process of determining what a user is allowed to do. .NET Core supports a number of authorization strategies, including:

- **Role-based access control (RBAC):** Users are assigned roles, and each role has a set of permissions.
- **Claims-based authorization:** Users are assigned claims, and each claim has a set of permissions.
- **Policy-based authorization:** Users are evaluated against a set of policies, and each policy determines what actions the user is allowed to perform.

## Choosing the right authentication and authorization options

The right authentication and authorization options for your application will depend on your specific requirements. If you need to support a large number of users, you may want to consider using OAuth 2.0 or JWT bearer tokens. If you need to implement fine-grained access control, you may want to consider using RBAC or claims-based authorization.

## Securing your application

In addition to using the right authentication and authorization options, there are a number of other things you can do to secure your application, such as:

- **Encrypting sensitive data:** Encrypt any sensitive data, such as passwords, that is stored in your application.
- **Using HTTPS:** Always use HTTPS for all communication between your application and the user's browser.
- **Keeping your application up to date:** Keep your application up to date with the latest security patches.

By following these best practices, you can help to protect your application from unauthorized access.
