Secondary Logon: What Is It and How Does It Work?

Have you ever come across the term \"Secondary Logon\" while using your computer? If you've ever encountered an Application or Service that required secondary logon to function, then you might be curious about what it means and how it works. In this article, we will discuss secondary logon, the reason behind its existence, and how it works.

What Is Secondary Logon?

Secondary Logon, also known as RunAs service, is a Microsoft Windows feature that allows administrators or users with permission to run certain applications or services as a different user, without changing the currently logged-on user account. This is useful for running specific applications or services, such as those that require administrative privileges, without affecting the user's daily use of their account, which is usually non-administrator or standard user.

Why Does Secondary Logon Exist?

In the earlier versions of Windows, mostly Windows XP, users had administrative privileges by default. This made their systems vulnerable to malware or accidental deletion of files, which could cripple the whole system. With the introduction of UAC (User Account Control) in Windows Vista and continued in higher versions of Windows, administrators and standard users are separated, and users have restricted access to system files and settings. Secondary Logon was introduced to bridge the gap between these two accounts, so administrators can run specific applications as an administrator, and regular users can use their accounts without any interference.

How Does Secondary Logon Work?

As mentioned earlier, Secondary Logon allows administrators to run specific applications or services as a different user, without changing the current user account. To enable Secondary Logon, press Windows key + R to open the Run dialogue box, then type in \"services.msc\". Once the Services app is open, scroll down to \"Secondary Logon\" and right-click on it, then select \"Properties\" from the context menu. On the \"Properties\" window, set the Startup type to \"Automatic\", then click on the \"Start\" button to initiate the service.

Once Secondary Logon is running, you can use it to run specific applications or services as a different user. To do this, right-click on the application's or service's executable file, then click on \"Run as another user\". Enter the credentials for the user account that you want to use to run the application or service, then click on \"OK\". The application or service will then run under the credentials you provided without affecting the currently logged-on user account.

In conclusion, Secondary Logon is a useful feature in Windows that allows administrators to run specific applications or services as a different user without having to change the currently logged-on user account. This makes it possible for regular users to use their accounts without any interference or risk of damage to system files and settings. With this in mind, you now have a better understanding of what Secondary Logon is and how it works.
