# Device lock

An action block that locks the device, as if the lock screen timeout expired. The user will be forced to reenter the pattern, PIN or password when unlocking, use the Interact block with action Lock screen to only engage the “Smart lock”, i.e. fingerprint or face.

The fiber will proceed immediately without pause.

The locking may be delayed if another fiber has temporarily disabled the screen lock using the Screen lock set state block.

Caution! Test your flow before using this block, improper use may lock you out of your device.
