The user has several choices for identifying the language to be used for the instance, as described here.

To enable user-specific languages, first activate the I18N Translation plugins for the desired languages.
  • Language picker at login: If user-specific language is enabled, users see a choice list on the login page to select their language. To control display of the choice list on the login page, navigate to All > System Properties > UI Properties and use the property Show the language select box on the login page to allow the user to specify the language they would like to be logged in with.
  • Language picker in the user menu (Next Experience UI): Users can select their language from the user menu by navigating to Preferences > Language & Region. The user menu is located in the Next Experience Unified Navigation.
  • Language picker in the System Settings window (Core UI): Users can select their language in the General tab of the System settings window. Access this window by clicking the gear icon on the right edge of the banner.
  • Language setting on the user table: If you have users that require a different language in addition to the global language, you can specify a language for them in All > User Administration > Users. If the Language field isn't already on the form, you can configure the form and add it.

The Language field in the User [sys_user] table overrides the default global language for that user's sessions.

Note: Setting the language for the system guest user sets the language for both the login page and all users without a user role.
