Adding users to `trusted-users` is a bad idea, as they can modify things like substituters.

[https://nix.dev/manual/nix/2.32/command-ref/conf-file.html#conf-trusted-users](https://nix.dev/manual/nix/2.32/command-ref/conf-file.html#conf-trusted-users)

> > **Warning**
> 
> Adding a user to `trusted-users` is essentially equivalent to giving that user root access to the system. For example, the user can access or replace store path contents that are critical for system security.

Use [`allowed-users`](https://nix.dev/manual/nix/2.32/command-ref/conf-file.html#conf-allowed-users) instead.
