Silent SSO for sub-apps is implemented by providing a backend SSO entry that encodes the returnUrl into the state parameter and redirects to the authorization page, establishing a local session upon callback to automate access without repeated logins.

The OAuth callback flow works by handling backend callbacks and rendering a frontend SSO callback page that extracts the token from the URL hash, establishing the local session to complete the single sign-on across sub-domains.

The authentication token is securely transmitted via the URL hash during the SSO callback process, preventing it from being sent to the server in HTTP headers or query parameters and reducing exposure to server logs.

Yes, you can prevent infinite redirect loops during single sign-on by restricting each session to trigger the SSO flow only once, which includes built-in loop prevention and fallback logic for safe automated sign-on.

Silent single sign-on requires the user to already be authenticated on the main site; if not, the flow includes error handling and fallback logic to manage the failed automatic sign-on attempt gracefully.

The best way to reduce login friction in a multi-application architecture is to automate silent SSO using OAuth endpoints that redirect users with an existing session, streamlining access across sub-domains without manual re-authentication.
