A security application designed for devices running the Android operating system, it allows users to restrict access to individual applications. This functionality ensures that sensitive information contained within these applications remains protected from unauthorized access by requiring a PIN, password, or fingerprint authentication before opening the app.
The utility of such a mechanism lies in its capacity to enhance device security beyond the standard lock screen protection. It offers a layered approach, safeguarding personal data, financial information, and private communications. Its introduction stemmed from a growing need to control application-level access, particularly in scenarios involving shared devices or concerns about privacy breaches.
