A free app for Android, by Microsoft Corporation.

With the Remote Desktop app, you can easily access your PC from your Android device anytime and anywhere. It is a great app that can help increase your productivity as it will allow you to access your workspaces right at your fingertips. But first, you need to configure your PC for remote access. The same is required for other remote desktop clients, such as Azure Virtual Desktop, Windows 365, and admin-provided virtual apps.

You don’t have to worry about security as this app provides a secure connection to your data and applications. It also allows you to easily manage your connections and user account from the Connection Center.
