 # Project access tokens
 
-NOTE:
-Project access tokens are supported for self-managed instances on Free and above. They are also supported on GitLab SaaS Premium and above (excluding [trial licenses](https://about.gitlab.com/free-trial/)). Self-managed Free instances should review their security and compliance policies with regards to [user self-enrollment](../../admin_area/settings/sign_up_restrictions.md#disable-new-sign-ups) and consider [disabling project access tokens](#enable-or-disable-project-access-token-creation) to lower potential abuse.
