Yes, I will explain.
When you have organization accounts linked to your computer, it's often because you're using Microsoft 365 provided by your work or school. When logging into one of these Microsoft 365 apps, a pop-up may appear asking if you'd allow your organization to manage certain settings. Most people quickly click "OK" without paying much attention, but by doing so, you're essentially enrolling your device in your organization's Intune device management system.
Don’t worry. Don't let those big words scare you. This doesn’t mean your IT department can access your personal files or control your computer. However, it does allow them to apply security protocols to ensure the safety of organizational data. This is because, when using organizational Microsoft 365 apps, it is assumed that you might be working with sensitive documents on your personal computer. To protect these files, your organization may enforce security measures like requiring a PIN, setting PIN complexity rules, and enforcing regular PIN changes.
These practices are particularly important for businesses that must follow strict regulations, like HIPAA. If you don't need these security policies on your personal device, you can disconnect these accounts. The next time you sign into a Microsoft 365 app, select the option "for this app only." near the bottom of the pop up.
