Question details

Users need a way to secure their OneDrive files within the Microsoft 365 Copilot app using biometric authentication, such as a fingerprint lock, to prevent unauthorized access.

Product: Microsoft 365 Copilot, OneDrive
Device & OS: Samsung Android
Scenario: Accessing sensitive OneDrive files directly through the integrated file viewer in the Microsoft 365 Copilot mobile app.
Observed behavior: The Copilot app provides full access to OneDrive files without triggering the biometric fingerprint prompt that is normally required when opening the standalone OneDrive app.

Before you start

Ensure your device's operating system and the Microsoft 365 Copilot app are updated to the latest versions to check if Microsoft has recently rolled out built-in biometric security updates.

Solution 1Recommended

Use System-Level App Locks for the Copilot App

Since Copilot lacks a built-in fingerprint lock for OneDrive, you can use your device's native security features to lock the entire Copilot app.

Samsung devices offer a 'Secure Folder' feature that allows you to store apps behind a biometric wall. Placing the Copilot app in this folder ensures no one can open it without your fingerprint.

Open device settings

Navigate to your Samsung device's Settings app and scroll down to 'Security and privacy'.

Enable Secure Folder

Tap on 'Secure Folder' and follow the on-screen prompts to set it up using your Samsung account and fingerprint.

Add Microsoft 365 Copilot

Open the Secure Folder, tap the '+' (Add apps) icon, select the Microsoft 365 Copilot app, and tap 'Add'. You will now need a fingerprint to launch Copilot.

Third-Party Alternatives: If you are not using a Samsung device, you can achieve the same result using reputable third-party app locker applications from the Google Play Store.

Solution 2

Manually Sign Out of Your Authenticated Web Session

Signing out of the Copilot app after each use prevents unauthorized users from accessing your OneDrive files via the active session.

Frequently Asked Questions

Why doesn't the Copilot app require my fingerprint for OneDrive?

The Microsoft 365 Copilot app accesses your files using a background authenticated web session tied to your Microsoft account. Because it doesn't open the standalone OneDrive app directly, it bypasses any biometric locks you have set there.

Can I lock the Microsoft 365 Copilot app itself with a fingerprint?

Currently, the Microsoft 365 Copilot app does not have a built-in setting for biometric locks. However, you can use system-level features like Samsung's Secure Folder or third-party app lockers to require a fingerprint before the app can be opened.

Is it safe to leave my Microsoft account logged into Copilot?

If your phone is unlocked and someone gains access to it, they could potentially view your OneDrive files by opening the Copilot app. If you frequently leave your device unlocked or unattended, it is safer to sign out of the app after use or secure it with an app locker.

Will Microsoft add a fingerprint lock to the Copilot app in the future?

Microsoft continuously updates its applications based on user feedback. It is recommended to contact Microsoft Support to report this security oversight and request that biometric protection be added to Copilot's integrated file viewer.
