Project bot users are [GitLab-created service accounts](../../../subscriptions/self_managed/index.md#billable-users) and do not count as licensed seats.
For each project access token created, a bot user is created and added to the project with
- The email is set to `project{project_id}_bot@example.com`, for example `project123_bot@example.com`.
- For additional access tokens in the same project, the username is set to `project_{project_id}_bot{bot_count}`, for example `project_123_bot1`.
- For additional acess tokens in the same project, the email is set to `project{project_id}_bot{bot_count}@example.com`, for example `project123_bot1@example.com`
| `read_registry` | Allows read-access (pull) to [container registry](../../packages/container_registry/index.md) images if a project is private and authorization is required. |
| `write_registry` | Allows write-access (push) to [container registry](../../packages/container_registry/index.md). |
| `read_repository` | Allows read-only access (pull) to the repository. |
| `write_repository` | Allows read-write access (pull, push) to the repository. |
You may enable or disable project access token creation for all projects in a group in **Group > Settings > General > Permissions, LFS, 2FA > Allow project access token creation**.
Even when creation is disabled, you can still use and revoke existing project access tokens.
This setting is available only on top-level groups.
To create a group access token, run the following in a Rails console:
```ruby
admin = User.find(1) # group admin
group = Group.find(109) # the group you want to create a token for
bot = Users::CreateService.new(admin, { name: 'group_token', username: "group_#{group.id}_bot", email: "group_#{group.id}_bot@example.com", user_type: :project_bot }).execute # create the group bot user
# for further group access tokens, the username should be group_#{group.id}_bot#{bot_count}, e.g. group_109_bot2, and their email should be group_109_bot2@example.com
bot.confirm # confirm the bot
group.add_user(bot, :maintainer) # add the bot to the group at the desired access level
token = bot.personal_access_tokens.create(scopes:[:api, :write_repository], name: 'group_token') # give it a PAT
gtoken = token.token # get the token value
```
Test if the generated group access token works:
1. Pass the group access token in the `PRIVATE-TOKEN` header to GitLab REST APIs. For example:
- [Create an epic](../../../api/epics.md#new-epic) on the group.
- [Create a project pipeline](../../../api/pipelines.md#create-a-new-pipeline)
in one of the group's projects.
- [Create an issue](../../../api/issues.md#new-issue) in one of the group's projects.
1. Use the group token to [clone a group's project](../../../gitlab-basics/start-using-git.md#clone-with-https)
using HTTPS.
### Revoke a group access token
To revoke a group access token, run the following in a Rails console:
```ruby
bot = User.find_by(username: 'group_109_bot') # the owner of the token you want to revoke
token = bot.personal_access_tokens.last # the token you want to revoke
