OpenID example configurations

On this page you will find examples about how to set up Vikunja with a third-party OAuth 2.0 provider using OpenID Connect. To add another example, please edit this document and send a PR.

Authelia #

Vikunja Config:

auth:
  openid:
    enabled: true
    redirecturl: https://vikunja.mydomain.com/auth/openid/  <---- slash at the end is important
    providers:
      - name: Authelia
        authurl: https://login.mydomain.com
        clientid: <vikunja-id>
        clientsecret: <vikunja secret>

Authelia config:

- id: <vikunja-id>
description: Vikunja
secret: <vikunja secret>
redirect_uris:
  - https://vikunja.mydomain.com/auth/openid/authelia
scopes:
  - openid
  - email
  - profile

Google / Google Workspace #

Vikunja Config:

auth:
  openid:
    enabled: true
    redirecturl: https://vikunja.mydomain.com/auth/openid/  <---- slash at the end is important
    providers:
      - name: Google
        authurl: https://accounts.google.com
        clientid: <google-oauth-client-id>
        clientsecret: <google-oauth-client-secret>

Google config:

  • Navigate to https://console.cloud.google.com/apis/credentials in the target project
  • Create a new OAuth client ID
  • Configure an authorized redirect URI of https://vikunja.mydomain.com/auth/openid/google

Note that there currently seems to be no way to stop creation of new users, even when enableregistration is false in the configuration. This means that this approach works well only with an "Internal Organization" app for Google Workspace, which limits the allowed users to organizational accounts only. External / public applications will potentially allow every Google user to register.

Keycloak #

Vikunja Config:

auth:
  openid:
    enabled: true
    redirecturl: https://vikunja.mydomain.com/auth/openid/  <---- slash at the end is important
    providers:
      - name: Keycloak
        authurl: https://keycloak.mydomain.com/realms/<relam-name>
        logouturl: https://keycloak.mydomain.com/realms/<relam-name>/protocol/openid-connect/logout
        clientid: <vikunja-id>
        clientsecret: <vikunja secret>

Keycloak Config:

  • Navigate to the keycloak instance
  • Create a new client with the type OpenID Connect and a unique ID.
  • Set Client authentication to On
  • Set Root Url to https://vikunja.mydomain.com
  • Set Valid redirect URIs to /auth/openid/keycloak
  • Create the client the navigate to the credentials tab and copy the Client secret

Authentik #

Authentik Config:

  • Create a new Provider called "Vikunja" in Authentik
  • Set the Redirect URIs/Origins (RegEx) to https://vikunja.mydomain.com/auth/openid/authentik
  • Copy the Client ID and Client Secret

Vikunja Config:

auth:
  openid:
    enabled: true
    redirecturl: "https://vikunja.mydomain.com/auth/openid/"
    providers:
      - name: authentik
        authurl: "https://authentik.mydomain.com/application/o/vikunja"
        logouturl: "https://authentik.mydomain.com/application/o/vikunja/end-session/"
        clientid: "" # copy from Authetik
        clientsecret: "" # copy from Authentik

Note: The authurl that Vikunja requires is not the Authorize URL that you can see in the Provider. OpenID Discovery is used to find the correct endpoint to use automatically, by accessing the OpenID Configuration URL (usually https://authentik.mydomain.com/application/o/vikunja/.well-known/openid-configuration). Use this URL without the .well-known/openid-configuration as the authurl. Typically, this URL can be found in the metadata section within your identity provider.

Azure Entrada ID #

Vikunja Config:

auth:
  openid:
    enabled: true
    redirecturl: https://vikunja.mydomain.com/auth/openid/  # <---- slash at the end is important
    providers:
      - name: AzureAD
        authurl: https://sts.windows.net/<tenant_id>/
        clientid: <azure-client-id>
        clientsecret: <azure-client-secret>

Azure AD Config:

  • Navigate to the Azure Portal and create a new App Registration
  • Set the Redirect URI to https://vikunja.mydomain.com/auth/openid/azuread
  • Under API permissions, add the following delegated API permissions:
    • email
    • openid
    • profile
    • User.Read
  • Create a new client secret and copy its value
  • In Token configuration, add an optional claim:
    • Select ID, then email

Note: Replace <tenant_id> in the authurl with your Azure AD tenant ID. Ensure that the provider name in the Vikunja config matches the one used in the redirect URI (e.g., "azuread" in this example).
