Create a two Factor Authentication for your OneDrive. This way, someone using your computer would need your phone to access your OneDrive.
I have the same problem others have. I have multiple people using my PC at work and at home, and I have no privacy with my OneDrive files. Anyone using my PC can look at my private files on OneDrive. What if you had the option to turn on Two Factor Authentication on OneDrive? This way if you wanted to turn it on, whoever tries to access your OneDrive files, would need your phone... or access to your Microsoft Authenticator app. This would solve the problem with password protected file requests that I see many people asking for. It would also solve my problem with everyone at work using my PC having access to my personal OneDrive Files and Folders.
