Google Drive gained a new privacy feature for its iPhone and iPad users dubbed Privacy Screen which gives an extra layer of protection with Touch ID or Face ID authentication when launching the app.
You can have the new Privacy Screen feature appear at launch or delay it by 10 seconds, 1 minute or 10 minutes. The updated iPhone and iPad versions are already live on the App Store.
The new feature is part of the latest 4.2020.18204 build which also brings stability improvements and bug fixes. Google warns you that some aspects like notifications are not completely protected by Privacy Screen.
