How do you restrict access to your app so people can only edit records they added?

The option to set modify permissions to "when user is Record Owner" is correct because this setting ensures that a user can only edit records that they themselves created. In Quickbase, the record owner is the individual who adds a record to the application. By restricting modification rights in this way, you create a controlled environment where users cannot alter any records not associated with them, thus promoting accountability and preventing unauthorized changes to other users' records.

This is particularly useful in collaborative environments where multiple users interact with the same set of data, ensuring that each user's contributions are respected and protected. As a result, it helps maintain data integrity and security within the application.

Setting modify permissions to any other criteria, such as "Last Modified by" or "View Permissions," would not provide the same level of restriction and could allow users to edit records added by others, undermining the intended control over who can make changes to specific records.
