Configure GitHub OAuth2 authentication

There are numerous authentication methods available in Grafana to verify user identity. The authentication configuration dictates which users can access Grafana and the methods they can use for logging in. You can also configure Grafana to automatically update users’ roles and team memberships in Grafana based on the information returned by the auth provider integration.

When deciding on an authentication method, it’s important to take into account your current identity and access management system as well as the specific authentication and authorization features you require. For a complete list of the available authentication options and the features they support, refer to Configure authentication.

This topic describes how to configure GitHub OAuth2 authentication.

Before you begin

To follow this guide:


To configure GitHub authentication with Grafana, follow these steps:

  1. Create an OAuth application in GitHub.

  2. Set the callback URL for your GitHub OAuth app to http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/github.

    Ensure that the callback URL is the complete HTTP address that you use to access Grafana via your browser, but with the appended path of /login/github.

    For the callback URL to be correct, it might be necessary to set the root_url option in the [server]section of the Grafana configuration file. For example, if you are serving Grafana behind a proxy.

  3. Refer to the following table to update field values located in the [auth.github] section of the Grafana configuration file:

    client_id, client_secretThese values must match the client ID and client secret from your GitHub OAuth app.
    enabledEnables GitHub authentication. Set this value to true.

    Review the list of other GitHub configuration options and complete them, as necessary.

  4. Configure role mapping.

  5. Optional: Configure team synchronization.

  6. Restart Grafana.

    You should now see a GitHub login button on the login page and be able to log in or sign up with your GitHub accounts.

Configuration options

The table below describes all GitHub OAuth configuration options. Like any other Grafana configuration, you can apply these options as environment variables.

enabledNoWhether GitHub OAuth authentication is allowed.false
nameNoName used to refer to the GitHub authentication in the Grafana user interface.GitHub
iconNoIcon used for GitHub authentication in the Grafana user interface.github
client_idYesClient ID provided by your GitHub OAuth app.
client_secretYesClient secret provided by your GitHub OAuth app.
auth_urlYesAuthorization endpoint of your GitHub OAuth provider.
token_urlYesEndpoint used to obtain GitHub OAuth access token.
api_urlYesEndpoint used to obtain GitHub user information compatible with OpenID UserInfo.
scopesNoList of comma- or space-separated GitHub OAuth scopes.user:email,read:org
allow_sign_upNoWhether to allow new Grafana user creation through GitHub login. If set to false, then only existing Grafana users can log in with GitHub OAuth.true
auto_loginNoSet to true to enable users to bypass the login screen and automatically log in. This setting is ignored if you configure multiple auth providers to use auto-login.false
role_attribute_pathNoJMESPath expression to use for Grafana role lookup. Grafana will first evaluate the expression using the user information obtained from the UserInfo endpoint. If no role is found, Grafana creates a JSON data with groups key that maps to GitHub teams obtained from GitHub’s /api/user/teams endpoint, and evaluates the expression using this data. The result of the evaluation should be a valid Grafana role (Viewer, Editor, Admin or GrafanaAdmin). For more information on user role mapping, refer to Configure role mapping.
role_attribute_strictNoSet to true to deny user login if the Grafana role cannot be extracted using role_attribute_path. For more information on user role mapping, refer to Configure role mapping.false
allow_assign_grafana_adminNoSet to true to enable automatic sync of the Grafana server administrator role. If this option is set to true and the result of evaluating role_attribute_path for a user is GrafanaAdmin, Grafana grants the user the server administrator privileges and organization administrator role. If this option is set to false and the result of evaluating role_attribute_path for a user is GrafanaAdmin, Grafana grants the user only organization administrator role. For more information on user role mapping, refer to Configure role mapping.false
skip_org_role_syncNoSet to true to stop automatically syncing user roles.false
allowed_organizationsNoList of comma- or space-separated organizations. User must be a member of at least one organization to log in.
allowed_domainsNoList of comma- or space-separated domains. User must belong to at least one domain to log in.
team_idsNoString list of team IDs. If set, user has to be a member of one of the given teams to log in.
tls_skip_verify_insecureNoIf set to true, the client accepts any certificate presented by the server and any host name in that certificate. You should only use this for testing, because this mode leaves SSL/TLS susceptible to man-in-the-middle attacks.false
tls_client_certNoThe path to the certificate.
tls_client_keyNoThe path to the key.
tls_client_caNoThe path to the trusted certificate authority list.

Configure role mapping

Unless skip_org_role_sync option is enabled, the user’s role will be set to the role retrieved from GitHub upon user login.

The user’s role is retrieved using a JMESPath expression from the role_attribute_path configuration option. To map the server administrator role, use the allow_assign_grafana_admin configuration option. Refer to configuration options for more information.

If no valid role is found, the user is assigned the role specified by the auto_assign_org_role option. You can disable this default role assignment by setting role_attribute_strict = true. This setting denies user access if no role or an invalid role is returned.

To ease configuration of a proper JMESPath expression, go to JMESPath to test and evaluate expressions with custom payloads.

Role mapping examples

This section includes examples of JMESPath expressions used for role mapping.

Map roles using GitHub user information

In this example, the user with login octocat has been granted the Admin role. All other users are granted the Viewer role.

role_attribute_path = [login=='octocat'][0] && 'Admin' || 'Viewer'

Map roles using GitHub teams

In this example, the user from GitHub team my-github-team has been granted the Editor role. All other users are granted the Viewer role.

role_attribute_path = contains(groups[*], '@my-github-organization/my-github-team') && 'Editor' || 'Viewer'

Map server administrator role

In this example, the user with login octocat has been granted the Admin organization role as well as the Grafana server admin role. All other users are granted the Viewer role.

role_attribute_path = [login=='octocat'][0] && 'GrafanaAdmin' || 'Viewer'

Configure team synchronization

Note: Available in Grafana Enterprise and Grafana Cloud.

By using Team Sync, you can map teams from your GitHub organization to teams within Grafana. This will automatically assign users to the appropriate teams. Teams for each user are synchronized when the user logs in.

GitHub teams can be referenced in two ways:

  • @<org>/<slug>

For example, or @grafana/developers.

To learn more about Team Sync, refer to Configure team sync.
