How to limit information to the user

Hello, how can I limit my user to seeing only the data it contains, not all users. (the screenshot shows 2 entries, but I should only see Michael Philips)

Go over to Features on the right in the list properties and create a filter to show only the list rows where the email is the signed-in user.

Yes @Jaime is correct. You do have to set the authentication login to either Public with Email or Whitelist.
