We will discuss a systematic method to install Sectigo Code Signing Certificate for your application. First, let us understand what a Code Signing Certificate is!

Code Signing Certificate: A necessity for Windows apps!

A code signing certificate is a digital certificate that helps ensure your app’s authenticity. When you create and authorize your app, you must obtain and install a code signing certificate from a trusted authority. This certificate allows Windows Store apps downloaded from the Microsoft Store to be verified as being from an authorized developer.

When users install or open an app signed with a valid code signing certificate, they can “trust this publisher.” Users assume that your organization is trustworthy and the app’s code integrity is intact. If they choose not to trust the publisher, Windows will prompt them for credentials before displaying the app. So, ensuring a secure customer experience through a code signing certificate becomes crucial.

If a user installs your app and later chooses to “Untrust this publisher,” Windows will not allow them to access any of their stored data in the app anymore. Now that we know why you need a code signing certificate, let us understand why Sectigo is the best choice.
