The cookies are 'per-session' cookies, i.e. they are destroyed when you close your browser. If you have chosen the option for your browser not to accept such cookies, you will not benefit from this feature and will have to re-authenticate yourself each time you log in to a different client application of the authentication service. A persistent cookie may be created for your convenience in order to record your choice of language, and at your discretion, your email address.
