On 18 September the method of accessing the CERN TWiki service changed. Users must now authenticate with the CERN Single Sign On procedure (see https://cern.ch/authentication, using their CERN login instead of their AFS username and password.

To log on to TWiki with the CERN login, you can use your CERN account, e.g. the existing MAIL, NICE or AIS/EDH login, or your "external account" if you are a non-CERN external user, as for Simba mailing lists or Indico. External users without a CERN account may obtain an external account from http://cern.ch/cernaccount/Externals. One advantage of the new procedure is that a user whose AFS account has expired will still be able to access TWiki. Information about how to manage your CERN account can be found at http://cern.ch/cernaccount.

Please note that only registered TWiki users can now edit pages with TWiki. If you are not yet registered you will be prompted to do so before editing a page. The user details will be hidden from the internet and only be accessible to authenticated users.
