How to add entries to the database on the site without authentication?

Question

Database

Beginner web application developer (self-taught).
There is a site with news. News is stored in the database.
How to add new news (i.e. entries in the database), if the site does not provide for authentication (do not log in under the administrator)?

Answer 1

In any case, you will have to create an elementary admin panel. It's not hard. The option without authorization and confirmation of rights is excluded.

Answer 2

Direct database queries, but I'm not sure if that's safe.
