Job placement: delete/remove ”sign in” option

Dear WP Job Manager community,

For admin purposes I prefer not to have the ”sign in” possibility at the job placement section. Website visitors ( employers ) should only place title, location and description.

The first field is ”sign in” . I tried to use CSS with display: none , but then I remove all fields… Any ideas ?

Thanks in advance ??
