Recent developments indicate that an app lock feature for Google Pixel phones is in the works, allowing users to lock individual apps independently and potentially use biometric verification instead of traditional PINs and passwords. Currently, Pixel devices offer a feature called Private Space, accessible through settings, which creates a secure interface for apps but requires a separate password and does not allow notifications from locked apps. Users can enhance app security using in-app encryption options available in various applications or by utilizing third-party app lock solutions from the Play Store. Additionally, the Files by Google app provides a Safe Folder feature that allows users to secure specific data with a password.
