System Mode and User Mode in Salesforce

System Mode

  • System mode means running apex code by ignoring user’s permissions. For example, if logged in user does not have permission to one object but they will able to access that object.
  • In system mode, Apex code has access to all objects and fields permissions, field-level security, sharing rules aren’t applied for the current user. This is to ensure that code won’t fail to run because of hidden fields or objects for a user.
  • In Salesforce, all apex code run in system mode. It ignores user’s permissions. Only exception is anonymous blocks like developer console and standard controllers. Even runAs() method doesn’t enforce user permissions or field-level permissions, it only enforces record sharing.

  • In User mode, Profile level permissions, field-level security, and sharing rules are applied for the current user.
  • In Salesforce, only standard controllers and anonymous blocks like developer console run in user mode.
