As of the Shattered Space expansion (Fall 2024), Bethesda has begun implementing into the Starfield Creations store. When you download a paid or free mod from the in-game store, the Creations menu now displays a small shield icon next to the language pack. Hovering over it reveals: "This language pack has been verified against Bethesda’s master checksums."

Always download Language Packs that explicitly state they are "Plugin-less" or "String-only." These are the only true "Verified" packs that will survive future Starfield updates.
