Troubleshooting a Missing CA Certificate

Phones and tablets running Android 10 (2019) and Android 11 (2020) use a security feature to ensure you trust the Certificate Authorities (CA) being installed. The steps below are not required for supported Android version 9 (2018) or earlier.

A Parent needs to add the CA certificate to Android devices to ensure the internet activity Family Zone is monitoring is verified and encrypted. 

On the Child's Android phone or tablet:

  1. Open the Connect App
    If you were installing and see a Cannot install CA Certificates message, tap OK
  2. Tap the home screen button
  3. Open Chrome or a web browser
    Go to the http://home.tools diagnostic page
  4. At the Browser certificate message, tap INSTALL
  5. Go to the Android Settings > Connections (or Network)
  6. Tap in the Search
    Type CA certificate (not case-sensitive)
  7. Move down and tap on CA certificate
    Tap again on CA certificate
  8. At the privacy warning, tap Install anyway
    The Connect App uses the certificate to encrypt and verify the data from your Child's device
  9. In Select item, tap Downloads > ca_cert.crt
  10. Close the Android settings
    Tap the home screen button
  11. Open the Connect App and tap DONE
  12. Recommended, restart your Child's Android device to clear out any open settings

The Connect App will monitor your Child's online activity. Insights and Premium Members will see Usage, Apps, and reports. 

Premium Members can use default filtering or customize the filtering rules. Premium Members can also set up Device sharing between Family members. When a Family member uses their PIN to sign in to a Device, the Connect App will use this Family member's monitoring settings.
