## Can I use multiple identity providers with Docker SSO?
Expand All @@ -29,6 +29,16 @@ To turn on SSO in Docker, you need the following from your IdP:

If your certificate expires, contact your identity provider to retrieve a new X.509 certificate. Then update the certificate in the [SSO configuration settings](/manuals/enterprise/security/single-sign-on/manage.md#manage-sso-connections) in the Docker Admin Console.

### Workarounds if users are locked out

If the certificate has already expired and users cannot access Docker Hub to update the certificate:

- Contact Docker Support to help you regain access to update the certificate
- Sign in with your Docker username and password to access the Admin Console (if SSO enforcement is not turned on)
- Maintain a dedicated administrator account (sometimes called a "break-glass" or "guest user" account) that is not subject to SSO for emergency access

To prevent lockouts, monitor your certificate expiration dates and renew certificates before they expire.

## What happens if my IdP goes down when SSO is turned on?

If SSO is enforced, users can't access Docker Hub when your IdP is down. Users can still access Docker Hub images from the CLI using personal access tokens.
