How to Protect the Microsoft 365 App with a PIN on Android

Product: Microsoft 365 App
Device & OS: Android
Scenario: Securing personal or work documents in the Microsoft 365 app from unauthorized access on a shared or unlocked Android tablet or phone.
Observed behavior: The Microsoft 365 app currently lacks a built-in PIN or password protection feature, unlike the OneDrive mobile app.

Before you start

Check if your Android device's manufacturer provides a built-in app lock feature in the system settings, as this is the most secure and convenient way to lock apps without installing extra software.

Solution 1Recommended

Use the Built-in Android App Lock Feature

Leverage your Android device's native app locking capabilities to require a PIN, password, or biometric check when opening the Microsoft 365 app.

Many Android manufacturers (such as Samsung, Xiaomi, Oppo, and Vivo) include a native App Lock feature in their custom operating systems. This allows you to secure individual apps at the system level.

Open Settings

Go to your Android device's Settings menu.

Find Security or Privacy

Navigate to 'Privacy', 'Security', or 'Apps' depending on your specific device brand.

Enable App Lock

Locate the 'App Lock' feature and enable it by setting up a secure PIN, pattern, or fingerprint.

Select Microsoft 365

Scroll through the list of installed applications and toggle the switch next to Microsoft 365 to enforce the lock.

Use the Built-in Android App Lock Feature

System Security: Using the built-in app lock is highly recommended as it integrates seamlessly with your device's fingerprint or face unlock sensors.

Solution 2

Install a Third-Party App Locker

If your device does not have a built-in app lock feature, use a trusted app locker from the Google Play Store.

Solution 3

Submit a Feature Request to Microsoft

Request Microsoft to add native PIN protection directly to the Microsoft 365 app.
