Create an application in authentik. Create an OAuth2/OpenID provider with the following parameters:

Client Type: Confidential

If your Grafana is running in docker, set the following environment variables:

environment:
    GF_AUTH_GENERIC_OAUTH_ENABLED: "true"
    GF_AUTH_GENERIC_OAUTH_NAME: "authentik"
    GF_AUTH_GENERIC_OAUTH_CLIENT_ID: "<Client ID from above>"
    GF_AUTH_GENERIC_OAUTH_CLIENT_SECRET: "<Client Secret from above>"
    GF_AUTH_GENERIC_OAUTH_SCOPES: "openid profile email"
    GF_AUTH_GENERIC_OAUTH_AUTH_URL: "https://authentik.company/application/o/authorize/"
    GF_AUTH_GENERIC_OAUTH_TOKEN_URL: "https://authentik.company/application/o/token/"
    GF_AUTH_GENERIC_OAUTH_API_URL: "https://authentik.company/application/o/userinfo/"
    GF_AUTH_SIGNOUT_REDIRECT_URL: "https://authentik.company/application/o/<Slug of the application from above>/end-session/"
    # Optionally enable auto-login
    GF_AUTH_OAUTH_AUTO_LOGIN: "true"

If you are using a config-file instead, you have to set these options:

[auth]
signout_redirect_url = https://authentik.company/application/o/<Slug of the application from above>/end-session/
# Optionally enable auto-login
oauth_auto_login = true

[auth.generic_oauth]
name = authentik
enabled = true
client_id = <Client ID from above>
client_secret = <Client Secret from above>
scopes = openid email profile
auth_url = https://authentik.company/application/o/authorize/
token_url = https://authentik.company/application/o/token/
api_url = https://authentik.company/application/o/userinfo/
