How do I unlock an app?
Sordifense uses Android’s system authentication, including supported biometrics and device screen-lock methods when available. Protected apps automatically relock after you leave them.
Why does it ask for Accessibility access?
Sordifense uses Accessibility Service to detect when a selected app opens and show its authentication screen. It does not use that service to read messages, passwords, typed text, or the contents of other apps. You can disable access in Android settings.
Do I need an account?
No account is required. Your selected apps and protection settings stay on your device. Read the privacy policy →
