# Licensing

A paid Aikido subscription is required to use Aikido Images. Usage of Aikido Images is limited to the duration of your active subscription.

## Is a subscription required to access Aikido Images?

Yes. Aikido Images is a paid feature. Docker authenticates to Aikido's registry at `docker.aikido.io` using a workspace-specific token that is tied to your active subscription.

## What happens when a subscription ends?

It is permitted to continue to use the existing revisions of the Aikido Images already pulled into your software after your Aikido subscription ends. However, your token will stop working and you will no longer be able to pull new or updated versions of Aikido Images from Aikido's registry.
