Windows authentication and security

This password is encoded using Base64 and sent to the server. It is important to note that the Base64 encoding is not encryption. So the drawback of this mechanism is that the user name and password are sent in clear text unencrypted during communication.

Use the following procedure to create the sample. The following options will appear: Figure 1. So you can configure them manually from Windows Features under Internet Information Services Security options as in the following screenshot; Figure 1. Windows will show the Figure 1. Enter the temporarily created Windows account "test" as in Figure 1. Windows won't let the website open until you enter the correct user name and password.

Digest Authentication Digest Authentication, like Basic Authentication, requires the user to provide account information using a login dialog box that is displayed by the browser.

Unlike Basic Authentication, the user name and password are not transmitted in clear text. Instead, a cryptographically secure hash with this information is sent. We can implement this authentication by simply enabling this option in IIS as in the following screenshot. Windows is unable to store MD5 hashes of passwords for local accounts SAM database thus the limitation of Digest Authentication is that in IIS, it only functions when the virtual directory is being authenticated or controlled by a Windows Active Directory Domain Controller.

Digest Authentication protects users and applications from a variety of malicious attacks by incorporating a piece of information about the request as input to the hashing algorithm. Enabling and disabling digest authentication can also be done programmatically.

We can enable this authentication using the AppCmd command as in the following:. For desktop and website automation, an on-premises data gateway is required so that programs that are installed on the on-premises computers for example, browser extensions and Power Automate Desktop can be accessed from the Power Automate cloud-based service.

More information: Install an on-premises data gateway. This is the authentication for any automation that you use with Microsoft services. When the automation is run, it runs on behalf of the user who's running the automation and not the user who set up the automation originally.

This type of authentication is used for systems and services that have an independent system other than what's used with Microsoft and Azure Active Directory Azure AD , with a separate username and password. Sign-ins for services such as Google, Facebook, and Twitter all have their own methods for authentication. Some enterprise systems provide single sign-on SSO.

After entering a login name, you will have to choose either Windows authentication or SQL Server authentication. Select Windows authentication.
