Please note that lightweight accounts are no longer created automatically for people leaving CERN.
If you need an alternative authentication method, e.g. to access your tax certificates, please link an external account from the new CERN Users Portal, using the "Linked Accounts" tab.

The password change pages have been moved to the new CERN Users Portal.

Login Restrictions

All logins must be at least 3 characters long, start with a letter and contain only letters and numbers.

The maximum length of the login varies with the account type.

Primary accounts logins are limited to 8 characters, to ensure compatibility with all existing applications.

Secondary and Service accounts can have logins up to 15 characters, but logins longer than 8 characters could cause problems with some applications or services.

Known limitations:

  • If the login is longer than 8 characters, you might not be able to create an AFS workspace for the account in some project (project-specific restrictions will apply). Personal AFS workspaces, instead, will work for any login.
