</span>I don't believe browsers meaningfully protect cookies at this point, given the intentional circumvention of same-origin policy as a routine development strategy, the amount of malware on machines, etc. YMMV and I'm sure others' do.<br>

The cookie plus the stored data associated with it is the only thing securing a session with the IdP and that's what provides SSO. If the stored data is on the server, then the cookie is a longish-lived bearer token and the only theft mitigation is client address.<br></blockquote><div><div class="gmail_default" style="font-family:courier new,monospace;display:inline">Can you elaborate on "stored data is on the server"? would this be "idp.session.StorageService = shibboleth.StorageService"<br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

If Local Storage is equally vulnerable to theft, which is likely, then having that data on the client doesn't affect this risk much.<br></blockquote><div><div class="gmail_default" style="font-family:courier new,monospace;display:inline">Would this be the case if server being set to "idp.session.StorageService = shibboleth.ClientSessionStorageService"</div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
