Prerequisites

I have searched the existing Closed AND Open Issues AND Discussions
I have searched and read the documentation

Vaultwarden Support String

SSO button not showing

Vaultwarden Build Version

tried all latest, testing and downgrading versions

Deployment method

Official Container Image

Custom deployment method

I am unable to see the Single Sign-On (SSO) button in the Vaultwarden web interface. This issue occurs across multiple platforms and versions I have tested:

Windows 10/11

macOS (local Mac Mini)

Ubuntu (local VM and EC2 instance)

I have tested:

Latest stable releases

Older stable releases

Development/testing Docker images

Despite verifying my SSO configuration (Keycloak/Entra ID/Authentik, etc.) and clearing browser cache, the SSO button does not appear. The login works fine through browser extensions and mobile apps, but the web UI remains without the SSO option.

Steps to Reproduce:

Install or update Vaultwarden to any version (stable, old stable, or testing image).

Configure SSO via your provider (Keycloak, Entra ID, etc.).

Access the Vaultwarden web interface.

Observe that the "Use Single Sign-On" button is missing.

Expected Behavior:
The web UI should display the SSO login button when SSO is configured correctly.

Actual Behavior:
The SSO button is not visible in the web interface, despite SSO being functional in other clients (browser extension, mobile app).

Environment:

Vaultwarden versions tested: All stable versions and testing/development images

Deployment method: Docker / Manual installation / Other

Browser: latest

Operating systems tested: Windows, macOS, Ubuntu, EC2 Ubuntu

Additional Notes:

I have tried clearing cache and accessing via multiple browsers.

Other users have reported that SSO works on some versions and setups, indicating this may be environment-specific or a UI bug.

both UI is loading and working just not showing the SSO button.

It's only available in testing and you also have to enable SSO for the button to be displayed.

@stefan0xC commented on GitHub (Sep 8, 2025): It's only available in `testing` and you also have to [enable SSO](https://github.com/dani-garcia/vaultwarden/wiki/Enabling-SSO-support-using-OpenId-Connect) for the button to be displayed.

I have the same issue.

After opening the page I get the following screen:

And entering the mail and master password (I get not redirected or anything just prompted to enter, this is a fresh installation with no user setup) it is confirmed that SSO_ONLY works...

Try to clear your cache, or use an InCognito/Private Browser Window. Bitwarden clients cache some settings, which could cause strange issues like this.

Your browser might have an old version of /css/vaultwarden.css still cached. Can you fully reload the web-vault and check again? If it does not change anything please post the support string that you can generate via the /admin/diagnostics page (after enabling it).
