In the previous chapter, we covered the last part of the Create and Deploy Apps objective by covering how to design and develop apps that run in containers. We've covered how to implement an application that runs on Azure Container Instances and we created an Azure Kubernetes Service and deployed an application to the cluster. 

In this chapter, we are going to start with the Implement Authentication and Secure Data objective. We are going to cover how to implement authentication for your web apps, APIs, functions, and logic apps, using certificates, forms-based authentication, and more. We are going to implement managed identities for Azure resources service principal authentication and implement multi-factor authentication and OAuth2 authentication.

The following topics will be covered in this chapter:

• Understanding Azure App Service authentication
• Implementing Windows-integrated authentication
• Implementing authentication by using certificates
• Understanding and implementing OAuth2 authentication in Azure AD
• Implementing tokens
• Understanding managed identities
• Implementing managed identities for Azure resources service principal authentication
