# Installing on Chromebooks from the Google Admin console without Basispoort

|| Please note! We recommend [using the Basispoort link](/en/article/installing-the-extension-on-chromebooks-for-use-with-basispoort-google-workspace-ilhz1h/)! Only use the instructions below if it is not possible to use Basispoort in your situation.
## What do you need?

**Extension**
An extension is installed for every student account. This extension will filter the internet on the laptops.

**Class code**
Every Myndr Switch has a unique class code. By entering it, the extension knows which switch to 'listen' to. This class code is printed on the back of the Myndr Switch itself.

|| Always start by turning the Myndr Switches to mode 5! That is the mode in which all the dots have the same colour. Once the extension has been installed and linked, it starts working immediately. You may want to take this into account in your planning too.
If you can't or don't want to carry out the steps below entirely on your own, we are happy to do it together with you. [Get in touch with us](https://www.myndr.nl/contact).

# 1

**Manage the correct group**
Go to [admin.google.com/ac/chrome/apps/user](https://admin.google.com/ac/chrome/apps/user) and select the group (organisational unit) where you want to install the extension:

# 2

**Add a new extension**
Once you have selected the correct group, hover your mouse over the large plus sign at the bottom right of the page. A number of icons now appear above the plus sign; click the grid icon.

# 3

**Enter the ID**
A dialog appears; enter the ID of the extension:

![](https://storage.crisp.chat/users/helpdesk/website/5d85cd828c1b4400/extensie-id_a6vxma.png)

Enter the code below as the Extension ID:

```
afphljjmbndfchfkdpegkckkcbejepik
```

Click SAVE

# 4

Under Installation policy (in the middle), choose Force install + pin.
That way you can be sure that everyone in the group gets the extension installed.

# 5

If your school allows Incognito mode on student devices, also tick the box here to make the extension mandatory in Incognito mode.
[For Myndr to work properly, however, we recommend disabling Incognito mode](/en/article/setting-requirements-for-google-workspace-bu42y/)!

# 6

**Link to the Myndr Switch**
You now need to configure the extension so that it is immediately linked to the correct Myndr Switch.

Copy the "script" below:

```
{"ClassroomCode":{"Value":"CODE"}}
```

Now scroll down on the right-hand side of the Admin console until you see "Policy for extensions", paste the script there and replace the word CODE with the class code for this OU:

![](https://storage.crisp.chat/users/helpdesk/website/5d85cd828c1b4400/classroomcode-invullen_n4filn.png)

# 7

Click **SAVE** at the very top right of the window

![](https://storage.crisp.chat/users/helpdesk/website/5d85cd828c1b4400/opslaan-2_y8mw4z.png)

The extension will now be installed for all accounts within the organisational unit. This can take a few minutes.
