To store access keys in a DB or in configs?

Question

PHP

There is a script that has access to stores using the token key. There are several such stores. Where is it better to store this token in terms of security, in the database or create a separate config, and store only the key ID from the config in the database?

Answer 1

Of course in the config. And store the config in encrypted form on a separate server with limited access by IP. Get a config via API with a temporary token.
