Android app protection policy settings in Microsoft Intune

This article describes the app protection policy settings for Android devices. The policy settings that are described can be configured for an app protection policy on the Settings blade in the Azure portal. There are two categories of policy settings: data protection settings and access settings. In this article, the term policy-managed apps refers to apps that are configured with app protection policies.

Data protection settings

Setting How to use Default value(s)
Prevent Android backups Select Yes to prevent this app from backing up work or school data to the Android Backup Service.

Select No to allow this app to back up work or school data.
Yes
Allow app to transfer data to other apps Specify what apps can receive data from this app:
  • Policy managed apps: Allow transfer only to other policy-managed apps.
  • All apps: Allow transfer to any app.
  • None: Do not allow data transfer to any app, including other policy-managed apps.

There are some exempt apps and services to which Intune may allow data transfer by default. In addition, you can create your own exemptions if you need to allow data to transfer to an app that doesn't support Intune APP. See Data transfer exemptions for more information.

This policy may also apply to Android App Links. General web links are managed by the Restrict web content transfer with other apps policy setting.

Note: Intune doesn't currently support the Android Instant Apps feature. Intune will block any data connection to or from the app. See the Android Developer documentation for more information about Android Instant Apps.

All apps
Allow app to receive data from other apps Specify what apps can transfer data to this app:
  • Policy managed apps: Allow transfer only from other policy-managed apps.
  • All apps: Allow data transfer from any app.
  • None: Do not allow data transfer from any app, including other policy-managed apps.

There are some exempts apps and services from which Intune may allow data transfer. See Data transfer exemptions for a full list of apps and services.

All apps
Prevent "Save As" Choose Yes to disable the use of the Save As option in this app. Choose No if you want to allow the use of Save As. Note: This setting is supported for Microsoft Excel, OneNote, PowerPoint, and Word. It may also be supported by third-party and LOB apps.

Select which storage services corporate data can be saved to
Users can save to the selected services (OneDrive for Business, SharePoint, and Local Storage). All other services will be blocked.

No

 

 

0 selected
Restrict cut, copy, and paste with other apps Specify when cut, copy, and paste actions can be used with this app. Choose from:
  • Blocked: Do not allow cut, copy, and paste actions between this app and any other app.
  • Policy managed apps: Allow cut, copy, and paste actions between this app and other policy-managed apps.
  • Policy managed with paste in: Allow cut or copy between this app and other policy-managed apps. Allow data from any app to be pasted into this app.
  • Any app: No restrictions for cut, copy, and paste to and from this app.
Any app
Restrict web content transfer with other apps Specify how web content (http/https links) are opened from policy-managed applications. Choose from:
  • Policy managed browsers: Allow web content to open only in policy-managed browsers.
  • Any app: Allow web links in any app


If you're using Intune to manage your devices, see Manage Internet access using managed browser policies with Microsoft Intune.

Policy-managed browsers
If you deploy multiple policy-managed browsers, only one will be launched. The launch order will be Intune Managed Browser and then Microsoft Edge. On Android, your end users can choose from other policy-managed apps that support http/https links if neither Intune Managed Browser nor Microsoft Edge are installed.

If a policy-managed browser is required but not installed, your end users will be prompted to install the Intune Managed Browser.

If a policy-managed browser is required, Android App Links are managed by the Allow app to transfer data to other apps policy setting.

Intune device enrollment
If you are using Intune to manage your devices, see Manage Internet access using managed browser policies with Microsoft Intune.

Policy-managed Microsoft Edge
The Microsoft Edge browser for mobile devices (iOS and Android) supports Intune app protection policies. Users who sign in with their corporate Azure AD accounts in the Microsoft Edge browser application will be protected by Intune. The Microsoft Edge browser integrates the MAM SDK and supports all of its data protection policies, with the exception of preventing:

  • Save-as: The Microsoft Edge browser does not allow a user to add direct, in-app connections to cloud storage providers (such as OneDrive).
  • Contact sync: The Microsoft Edge browser does not save to native contact lists.

Note:
The APP SDK cannot determine if a target app is a browser. On Android devices, other managed browser apps that support the http/https intent are allowed.
Any app
Encrypt app data Choose Yes to enable encryption of work or school data in this app. Intune uses an OpenSSL, 256-bit AES encryption scheme along with the Android Keystore system to securely encrypt app data. Data is encrypted synchronously during file I/O tasks. Content on the device storage is always encrypted. The SDK will continue to provide support of 128-bit keys for compatibility with content and apps that use older SDK versions.

The encryption method is not FIPS 140-2 certified.
Yes
Disable app encryption when device encryption is enabled Choose Yes to disable app encryption for internal app storage when device encryption is detected on an enrolled device.

Note: Intune can only detect device enrollment with Intune MDM. External app storage will still be encrypted to ensure data cannot be accessed by unmanaged applications.
Yes
Disable contact sync Choose Yes to prevent the app from saving data to the native Contacts app on the device. If you choose No, the app can save data to the native Contacts app on the device.

When you perform a selective wipe to remove work, or school data from the app, contacts synced directly from the app to the native Contacts app are removed. Any contacts synced from the native address book to another external source can't be wiped. Currently this applies only to the Microsoft Outlook app.
No
Disable printing Choose Yes to prevent the app from printing work or school data. No

Note

The encryption method for the Encrypt app data setting is not FIPS 140-2 certified.

Data transfer exemptions

There are some exempt apps and platform services that Intune app protection policy may allow data transfer to and from. For example, all Intune-managed apps on Android must be able to transfer data to and from the Google Text-to-speech, so that text from your mobile device screen can be read aloud. This list is subject to change and reflects the services and apps considered useful for secure productivity.

Access settings

Setting How to use
Require PIN for access Select Yes to require a PIN to use this app. The user is prompted to set up this PIN the first time they run the app in a work or school context.

Default value = Yes.

Configure the following settings for PIN strength:
  • Select Type: Set a requirement for either numeric or passcode type PINs before accessing an app that has app protection policies applied. Numeric requirements involve only numbers, while a passcode can be defined with at least 1 alphabetical letter or at least 1 special character.

    Default value = Numeric

    Note: Special characters allowed include the special characters and symbols on the Android English language keyboard.
  • Number of attempts before PIN reset: Specify the number of tries the user has to successfully enter their PIN before they must reset it.

    Default value = 5

  • Allow simple PIN: Select Yes to allow users to use simple PIN sequences like 1234, 1111, abcd or aaaa. Select No to prevent them from using simple sequences.

    Default value = Yes

    Note: If Passcode type PIN is configured, and Allow simple PIN is set to Yes, the user needs at least one letter or at least one special character in their PIN. If Passcode type PIN is configured, and Allow simple PIN is set to No, the user needs at least one number and one letter and at least one special character in their PIN.

  • PIN length: Specify the minimum number of digits in a PIN sequence.

    Default value = 4

  • Allow fingerprint instead of PIN (Android 6.0+): Select Yes to allow the user to use fingerprint authentication instead of a PIN for app access.

    Default value = Yes

    Note: This feature supports generic controls for biometric on Android devices. OEM-specific biometric settings, like* Samsung Pass, are not supported.

    On Android, you can let the user prove their identity by using Android fingerprint authentication instead of a PIN. When the user tries to use this app with their work or school account, they are prompted to provide their fingerprint identity instead of entering a PIN.

    Android work profiles require registering a separate fingerprint for the Allow fingerprint instead of PIN policy to be enforced. This policy takes effect only for policy-managed apps installed in the Android work profile. The separate fingerprint must be registered with the device after the Android work profile is created by enrolling in the Company Portal. For more information about work profile fingerprints using Android work profiles, see Lock your work profile.
Require corporate credentials for access Choose Yes to require the user to sign in with their work or school account instead of entering a PIN for app access. When set to Yes, and PIN or biometric prompts are turned on, both corporate credentials and either the PIN or biometric prompts are shown.

Default value = No
Recheck the access requirements after (minutes) Configure the following setting:
  • Timeout: This is the number of minutes before the access requirements (defined earlier in the policy) are rechecked. For example, an admin turns on PIN and Blocks rooted devices in the policy, a user opens an Intune-managed app, must enter a PIN, and must be using the app on a non-rooted device. When using this setting, the user won't have to enter a PIN or undergo another root-detection check on any Intune-managed app for a period of time equal to the configured value.

    This policy setting format supports a positive whole number.

    Default value = 30 minutes

    Note: On Android, the PIN is shared with all Intune-managed apps. The PIN timer is reset once the app leaves the foreground on the device. The user won't have to enter a PIN on any Intune-managed app that shares its PIN for the duration of the timeout defined in this setting.*

Block screen capture and Android Assistant Select Yes to block screen capture and the Android Assistant capabilities of the device when using this app. Choosing Yes will also blur the App-switcher preview image when using this app with a work or school account.

Default value = No

Note

To learn more about how multiple Intune app protection settings configured in the Access section to the same set of apps and users work on Android, see Intune MAM frequently asked questions and Selectively wipe data using app protection policy access actions in Intune.

Conditional launch

Configure conditional launch settings to set sign-in security requirements for your access protection policy.

By default, several settings are provided with pre-configured values and actions. You can delete some of settings, like the Min OS version. You can also select additional settings from the Select one dropdown.

Setting How to use
Max PIN attempts Specify the number of tries the user has to successfully enter their PIN before the configured action is taken. This policy setting format supports a positive whole number. Actions include:
  • Reset PIN - The user must reset their PIN.
  • Wipe data - The user account that is associated with the application is wiped from the device.
Default value = 5
Offline grace period The number of minutes that MAM apps can run offline. Specify the time (in minutes) before the access requirements for the app are rechecked. Actions include:
  • Block access (minutes) - The number of minutes that MAM apps can run offline. Specify the time (in minutes) before the access requirements for the app are rechecked. After this period expires, the app requires user authentication to Azure Active Directory (Azure AD) so that the app can continue to run.

    This policy setting format supports a positive whole number.

    Default value = 720 minutes (12 hours)
  • Wipe data (days) - After this many days (defined by the admin) of running offline, the app will require the user to connect to the network and reauthenticate. If the user successfully authenticates, they can continue to access their data and the offline interval will reset. If the user fails to authenticate, the app will perform a selective wipe of the users account and data. For more information, see How to wipe only corporate data from Intune-managed apps.
This policy setting format supports a positive whole number.

Default value = 90 days This entry can appear multiple times, with each instance supporting a different action.
Jailbroken/rooted devices There is no value to set for this setting. Actions include:
  • Block access - Prevent this app from running on jailbroken or rooted devices. The user continues to be able to use this app for personal tasks, but will have to use a different device to access work or school data in this app.
  • Wipe data - The user account that is associated with the application is wiped from the device.
Min OS version Specify a minimum Android operating system that is required to use this app.. Actions include:
  • Warn - The user will see a notification if the Android version on the device doesn't meet the requirement. This notification can be dismissed.
  • Block access - The user will be blocked from access if the Android version on the device doesn't meet this requirement.
  • Wipe data - The user account that is associated with the application is wiped from the device.
This policy setting format supports either major.minor, major.minor.build, major.minor.build.revision.
