# EphemeralBrowserSessionIsSupported

A Boolean that indicates whether the app supports ephemeral browsing when conducting authentication sessions.

## Discussion

Discussion Set the corresponding value to YES to indicate that your browser app, when handling authentication requests, offers ephemeral browsing. If you don’t provide the key, or if you set its value to NO and an app tries to conduct an ephemeral authentication session, the system warns the user. If do you declare support by setting the value to YES, be sure to respect the shouldUseEphemeralSession property on any incoming authentication requests, as described in Supporting Single Sign-On in a Web Browser App. note: It’s strongly recommended that your web browser support ephemeral sessions. Apps can specifically request this kind of session, and it’s important to honor the request.
