Lock All Devices with one code

Your user code links your devices together. Tap Lock All Devices and every phone and tablet with the same code locks — including the one in your hand.

  • Add as many Android phones and tablets to a code as you like
  • Works across Wi-Fi and mobile data via Firebase Cloud Messaging
  • No account, e-mail or phone number required

Lock from the website

When none of your devices is at hand, open the lock page on any browser and enter your code. The command reaches your devices the same way as from the app.

  • Any computer, phone or tablet with a browser
  • Hold-to-lock confirmation prevents accidental locks
  • Code is not stored; attempts are rate-limited

Scheduled lock at an exact time

Select Date and Time, then Save Lock Setting. Android’s exact alarm wakes the device and locks the screen right on time.

  • Exact-alarm precision on Android 12 and later
  • Schedule is restored automatically after a restart
  • Perfect for bedtime, exams and focus sessions

Biometric protection for the app

Lock My Devices asks for your fingerprint, face or device screen lock before it opens, so nobody else can change your code or settings.

  • Uses Android’s BiometricPrompt
  • No biometric data is stored or shared by the app
  • Falls back to your PIN, pattern or password

Minimal, transparent permissions

The device administrator policy is limited to a single right: force lock. The app cannot wipe data, change passwords or watch what you do.

  • Device admin: “force-lock” only
  • Exact alarm, boot, wake-lock and notifications for scheduled locks
  • Internet only to register the device and receive lock commands
