Your token can be seen at https://factorio.com/profile (after logging in). It is not as sensitive as your password, but should still be safeguarded. There is a link on that page to revoke/invalidate the token, if you believe it has been leaked or wish to take precautions. Example: { packageOverrides = pkgs: { factorio = pkgs.factorio.override { username = "FactorioPlayer1654"; token = "d5ad5a8971267c895c0da598688761"; }; }; } Alternatively, instead of providing the username+token, you may manually download the release through https://factorio.com/download , then add it to the store using e.g.: releaseType=alpha version=0.17.74 nix-prefetch-url file://\''$HOME/Downloads/factorio_\''${releaseType}_x64_\''${version}.tar.xz --name factorio_\''${releaseType}_x64-\''${version}.tar.xz Note the ultimate "_" is replaced with "-" in the --name arg!
