Bitwarden

Tested Versions

Authelia
- v4.39.19
Bitwarden
- v2025.7.3

Assumptions

This example makes the following assumptions:

Application Root URL: https://bitwarden.{{< sitevar name="domain" nojs="example.com" >}}/
Authelia Root URL: https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/
Client ID: bitwarden
Client Secret: insecure_secret

{{< callout context="tip" title="Did you know?" icon="outline/rocket" >}} This setup assumes you're using the self-hosted version of Bitwarden. If you're using the SaaS version the redirect_uris are either usually https://sso.bitwarden.com/oidc-signin or if you're in the EU https://sso.bitwarden.eu/oidc-signin. {{< /callout >}}

Some of the values presented in this guide can automatically be replaced with documentation variables.
