# Authorising and de-authorising

### Authorising Liberation

When you open Liberation for the first time, it'll run in *demo mode* and you'll see the *About panel:*

Click on the *AUTHORISE ONLINE* button and your web browser will open. If you are not already logged in, you will be prompted to do so now.

The system will now automatically authorise your installation with your subscription, and you'll see this message:

When you return to Liberation you'll see the *About panel* has updated (you may have to wait a few seconds).

{% hint style="warning" %}
If you have already authorised the maximum number of computers for your subscription, you will need to deauthorise one of your other machines or upgrade your subscription.
{% endhint %}

{% hint style="info" %}
If you have multiple subscriptions, you will be prompted to choose the subscription that you want to assign the computer.
{% endhint %}

Congratulations! Your Liberation install has now been authorised and you can output to lasers! But please read the [getting-started](https://docs.liberationlaser.com/getting-started "mention")and [setting-up-lasers](https://docs.liberationlaser.com/setting-up/setting-up-lasers "mention") before arming your lasers.

{% hint style="info" %}
You can open the *About panel* at any time via the menu *Liberation -> About Liberation* or *Liberation -> Authorise/Deauthorise this computer*
{% endhint %}

### De-authorising Liberation

**From within Liberation** - Open the menu *Liberation -> Authorise / De-authorise this Computer* and click the *DEAUTHORISE COMPUTER* button. That's it! You need to be online for this to work.

Alternatively you can do this from the website - Select *Your subscriptions* from the menu, and then click *Manage Subscription* to open your subscription page. You should see information about your subscription and a list of the computers you have authorised.

Click the *De-authorise* link next to the machine you want to de-authorise

If your machine hasn't been online since your last renewal it will be deauthorised immediately. If not, then the machine is *queued* for deauthorisation. This means that deauthorisation will automatically happen next time the machine is connected to the internet, or on your next renewal date, whichever happens first.
