Scroll to Mobile Application Security and choose from the security options:

  • Disable message preview on mobile device's lock screen—Users won't be able to choose the Show message preview option in the Webex App mobile apps.
  • Disable the use of unmanaged app—Users are required to use a corporate managed version of Webex. They won't be able to use the unmanaged Webex apps (downloaded from Apple App Store / Google Play Store).


    If you use this setting, you must also sign in to your Enterprise Mobility Management (EMM) console to configure the following App Config parameters for both iOS and Android versions. This App Config parameter allows Webex services to detect that the Webex App is managed by EMM, and to block access on unmanaged devices.
