 OIDC providers typically require applications to be identified and authenticated when they interact with the OIDC endpoints.

+[[state-cookies]]
+==== State cookies
+
+State cookies are used to support authorization code flow completion.
+When an authorization code flow is started, Quarkus creates a state cookie and a matching `state` query parameter, before redirecting the user to the OIDC provider.
+When the user is redirected back to Quarkus to complete the authorization code flow, Quarkus expects that the request URI must contain the `state` query parameter and it must match the current state cookie value.
+
+The default state cookie age is 5 mins and you can change it with a `quarkus.oidc.authenticaion.state-cookie-age` Duration property.
+
+Quarkus creates a unique state cookie name every time a new authorization code flow is started to support multi-tab authentication. Many concurrent authentication requests on behalf of the same user may cause a lot of state cookies be created.
+If you do not want to allow your users use multiple browser tabs to authenticate then it is recommended to disable it with `quarkus.oidc.authenticaion.allow-multiple-code-flows=false`. It also ensures that the same state cookie name is created for every new user authentication.
