If the password must be available to the script without human intervention, the best you can get will only "protect" it from casual observation. Putting it in a file only the "script runner" can read is only workable if the user id the script runs under is dedicated to running that script. In particular, that user ID must not be used for a "normal" user login.
Usually, it is much better that a trusted staff member supply the password when the script is started. Of course, that is only practical if the script is either a long running, start-and-forget task, or is run very infrequently.
Also, any situation where the script fetches the password from some kind of password manager is just shifting the problem. The script still has to authenticate itself to the password manager.
