what is the difference between system mode and user mode?

Hi,

System Mode basically runs Apex code while ignoring the user’s permissions and privileges. In the System Mode, Apex code will have access to all the fields and objects while sharing rules and field security aren’t applied to the current user.

All Apex code runs on System Mode and this ensures that the code won’t fail to run because of hidden objects for the user or hidden fields. The only exceptions here are anonymous blocks like standard controllers and developer consoles.

In the User Mode, the code will be executed taking the privileges of the user into consideration. On the Salesforce platform, only Anonymous Apex and standard controllers can be executed in User Mode. In other words, it only runs Apex code by respecting the user’s permissions and sharing of records.

Hi,

To make it more simple -

User Mode - Profile level permissions, field-level security, and sharing rules of the current user are enforced.

System Mode - Object permissions, field-level security, sharing rules aren't applied for the current user.

Hope this helps.
