Configure Google OAuth2 authentication

To enable Google OAuth2 you must register your application with Google. Google will generate a client ID and secret key for you to use.

Create Google OAuth keys

First, you need to create a Google OAuth Client:

1. Go to https://console.developers.google.com/apis/credentials.
2. Click Create Credentials, then click OAuth Client ID in the drop-down menu
3. Enter the following:
   • Application Type: Web Application
   • Name: Grafana
   • Authorized JavaScript Origins: https://grafana.mycompany.com
   • Authorized Redirect URLs: https://grafana.mycompany.com/login/google
   • Replace https://grafana.mycompany.com with the URL of your Grafana instance.
4. Click Create
5. Copy the Client ID and Client Secret from the ‘OAuth Client’ modal

Enable Google OAuth in Grafana

Specify the Client ID and Secret in the Grafana configuration file. For example:

[auth.google]
enabled = true
client_id = CLIENT_ID
client_secret = CLIENT_SECRET
scopes = https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
auth_url = https://accounts.google.com/o/oauth2/auth
token_url = https://accounts.google.com/o/oauth2/token
allowed_domains = mycompany.com mycompany.org
allow_sign_up = true

You may have to set the root_url option of [server] for the callback URL to be correct. For example in case you are serving Grafana behind a proxy.

Restart the Grafana back-end. You should now see a Google login button on the login page. You can now login or sign up with your Google accounts. The allowed_domains option is optional, and domains were separated by space.

You may allow users to sign-up via Google authentication by setting the allow_sign_up option to true. When this option is set to true, any user successfully authenticating via Google authentication will be automatically signed up.
