Users log in to a Model Manager server from the COMSOL Desktop environment or via a web browser using an account stored in the local settings database of the server. The account is created automatically if authenticating using External Authentication or Proxy Authentication. If using Local Authentication, a root administrator first needs to create each account via the web interface. A hashed account password is stored in the local settings database in this latter case — see Password Security. No account password is stored by the Model Manager server for the other authentication mechanisms.
