# Twitter OAuth 1.0a OmniAuth Provider **(FREE SELF)**
|
|
|
|
NOTE:
|
|
Twitter OAuth 2.0 support is [not supported](https://gitlab.com/gitlab-org/gitlab/-/issues/366213).
|
|
|
|
To enable the Twitter OmniAuth provider you must register your application with
|
|
Twitter. Twitter generates a client ID and secret key for you to use.
|
|
|
|
## Create a new Twitter application
|
|
|
|
1. Sign in to [Twitter Application Management](https://developer.twitter.com/apps).
|
|
|
|
1. Select **Create new app**.
|
|
|
|
1. Fill in the application details.
|
|
- **Name**: This can be anything. Consider something like `<Organization>'s GitLab`, `<Your Name>'s GitLab` or
|
|
something else descriptive.
|
|
- **Description**: Create a description.
|
|
- **Website**: The URL to your GitLab installation. For example, `https://gitlab.example.com`
|
|
- **Callback URL**: `https://gitlab.example.com/users/auth/twitter/callback`
|
|
- **Developer Agreement**: Select **Yes, I agree**.
|
|
|
|
|
|
|
|
1. Select **Create your Twitter application**.
|
|
|
|
## Configure the application settings
|
|
|
|
1. Select the **Settings** tab.
|
|
|
|
1. Underneath the **Callback URL**, select the **Allow this application to be used to Sign in with Twitter** checkbox.
|
|
|
|
1. Select **Update settings** to save the changes.
|
|
|
|
1. Select the **Keys and Access Tokens** tab.
|
|
|
|
1. Find your **API key** and **API secret**. Keep this tab open as you continue configuration.
|
|
|
|
|
|
|
|
## Configure your application on the GitLab server
|
|
|
|
1. On your GitLab server, open the configuration file.
|
|
|
|
For Omnibus package:
|
|
|
|
```shell
|
|
sudo editor /etc/gitlab/gitlab.rb
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```shell
|
|
cd /home/git/gitlab
|
|
|
|
sudo -u git -H editor config/gitlab.yml
|
|
```
|
|
|
|
1. Configure the [common settings](omniauth.md#configure-common-settings)
|
|
to add `twitter` as a single sign-on provider. This enables Just-In-Time
|
|
account provisioning for users who do not have an existing GitLab account.
|
|
|
|
1. Add the provider configuration.
|
|
|
|
For Omnibus package:
|
|
|
|
```ruby
|
|
gitlab_rails['omniauth_providers'] = [
|
|
{
|
|
name: "twitter",
|
|
# label: "Provider name", # optional label for login button, defaults to "Twitter"
|
|
app_id: "<your_api_key>",
|
|
app_secret: "<your_api_secret>"
|
|
}
|
|
]
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```yaml
|
|
- { name: 'twitter',
|
|
# label: 'Provider name', # optional label for login button, defaults to "Twitter"
|
|
app_id: '<your_api_key>',
|
|
app_secret: '<your_api_secret>' }
|
|
```
|
|
|
|
1. Change `<your_api_key>` to the API key from the Twitter **Keys and Access Tokens** tab.
|
|
|
|
1. Change `<your_api_secret>` to the API secret from the Twitter **Keys and Access Tokens** tab.
|
|
|
|
1. Save the configuration file.
|
|
|
|
1. For the changes to take effect, if you installed:
|
|
|
|
- Using Omnibus, [reconfigure GitLab](../administration/restart_gitlab.md#omnibus-gitlab-reconfigure).
|
|
- From source, [restart GitLab](../administration/restart_gitlab.md#installations-from-source).
|
|
|
|
On the sign-in page, find the Twitter option below the regular sign-in form. Select the option to begin the authentication process. Twitter asks you to sign in and authorize the GitLab application. After authorization,
|
|
you are returned to GitLab and signed in.
