SSO Feature Enabled but No SSO Button Appearing in UI

[Muhammad-Hashim]

Hello,

I am trying to enable the SSO feature in my vaultwarden but the SSO button does not appear in the UI even after enabling it.

Environment

• Server Version: 1.35.4
• Web Version: 2026.1.1
• Database: SQLite 3.50.2
• Installed via Docker (latest images pulled)

What I Did

1. Pulled the latest Docker images and restarted the containers.
2. Enable the SSO feature from the admin panel.

Problem

After enabling the feature and adding the email:

• The SSO button does not appear anywhere in the UI.
• I cannot find the SSO option in the login screen .

What I Expected

After enabling SSO and completing the email step, I expected the SSO button or control to appear in the UI so the feature could be used.

Additional Notes

• Containers appear healthy.
• Versions are fully up to date.
• No obvious errors are shown in the UI.

Question

• Is there an additional step required to make the SSO button appear in the UI?
• Could this be a configuration issue?

Any guidance would be appreciated.

It's not SOS but SSO (Single sign on).

Any guidance would be appreciated.

I would recommend restarting Vaultwarden (if you have not already tried that) and then force-reload the /css/vaultwarden.css so it' s updated.

Thanks for the correction — you’re right, it’s SSO (Single Sign-On). I’ve updated the description accordingly.

Also, thank you for the suggestion.

I tried restarting Vaultwarden, and I also performed a hard/force reload to refresh /css/vaultwarden.css, but unfortunately the issue is still the same. The SSO option still does not appear in the UI.

Is there any other step I might be missing or another way to troubleshoot this? I would really appreciate any further guidance.

Can you open the SSO page?
https://your.vault.domain.example.com/#/sso

Enter any random string and try SSO.

If you're publishing via a CDN such as Cloudflare, it may be cached there.

It was resolved after updating to the latest version. I was able to access the SSO page directly via /#/sso even though the SSO option wasn’t visible in the UI. It looks like the UI was heavily cached, which is why the button wasn’t appearing. Everything is working now. Thanks for the help.
