2 Certificate Install - Android v11

These instructions are for Android 11. There are separate certificate installation instructions for Android 9&10, Apple iPhones & Ipads, Apple Macs, Chromebooks and Windows devices.
To find out what version of Android you have, select Settings, About Phone, Software Version.

On your Android device, you may get security warnings when going to secure websites like 'There are problems with the security certificate for this site'. Secure websites have addresses that begin with 'https' and they show a padlock icon in your web browser's address bar once they've loaded. To load these sites without the error messages you need to install the N4L security certificate onto your device.

1. Ensure your device has a lock screen PIN, a swipecode or fingerprint access set up. Android won't let you install a certificate without one.

2. Ensure you are connected to Kerikeri High School's 'KKHS_Mahi' wifi, and have access to the school website at www.kerikerihigh.ac.nz. Instructions on how to do this are available here.

3. Open your device's web browser, and go to the School website at www.kerikerihigh.ac.nz by typing it all in to the address bar.

4. From the School website's 'Devices' menu select 'Download N4LCert.crt'.
A message saying 'Cant install CA certificates' will appear. Click 'OK'
The certificate will download into your device's Download folder.

5. Select Settings, Biometrics & Security, Other Security Settings, Install From Device Storage, and choose 'CA certificate'.

6. A 'Your privacy is at risk' message will appear. Click 'Install anyway' and verify with your fingerprint, swipe or PIN code.

7. The storage area will appear. Select the 'Download' folder and you will see the certificate downloaded earlier.
Select the certificate and click 'Done'.

8. Try going to a secure website, e.g. https://www.google.com
You should no longer get certificate security warnings.
 

*** If your Android device has the Family Link parental control app installed, and lockdown is being applied, you will not be able to download and install the certificate until Family Link is unlocked. This can be done at home where the certificate can then be installed by your parent or caregiver. The same instructions apply, except step 2. ***
 

These instructions were written using Android v11. The installation details may differ on other versions but the concepts are the same.
For help with setting up your device, especially the certificate install, see the IT Ninjas in the SMI Computer Room at lunchtime on Mondays and Fridays.
