+# Unlock
+
+Espresso driver allows dealing with the Android lock screen using various APIs.
+This article describes the available APIs and their options.
+
+## Unlock On Session Startup
+
+Espresso driver provides the following [capabilities](../../README.md#device-locking) to deal
+with the system lock screen:
+
+- appium:unlockSuccessTimeout
+- appium:skipUnlock
+- appium:unlockType
+- appium:unlockKey
+
+These capabilities could be used to unlock the device under test during the driver session initialization
+as well as deal with different lock screen types.
+
+### appium:unlockSuccessTimeout
+
+Maximum number of milliseconds to wait until the device is unlocked. `2000` ms by default
+
+### appium:skipUnlock
+
+The `appium:skipUnlock` capability is enabled by default and makes the driver to detect and handle the lock screen
+upon session startup _if it is present_. If the lock screen cannot be detected upon session startup then nothing will be
+done. By default, it is assumed the device has a "simple" lock screen, which could be removed by waking up the device.
+In case the device has a different type of the lock screen configured in its settings then the information about it
+must be provided in the below capability values.
+
+### appium:unlockType and appium:unlockKey
+
+This capability supports the following possible values:
+
+#### pin
+
+Assumes the device is protected with a PIN code. Expects the `appium:unlockKey` to contain a valid pin consisting
+of digits in range 0-9, for example `1111`.
+
+#### password
+
+Assumes the device is protected with a password. Expects the `appium:unlockKey` to contain a valid password consisting
+of latin characters, for example `abcd1234`.
+
+#### pattern
+
+Assumes the device is protected with a secret pattern. Check the example below for more details on the `appium:unlockKey`
+value for this particular unlock type.
+
+##### Example
+
+Let say you have a device that is locked with a pattern similar to the one on the image below,
+and you want to run a test over that device.
+
+<img src="./screen1.png" />
+
+We treat the pattern pins similarly to numbers on a digital phone dial. So, in this case the *unlockKey* is `729854163`
+
+<img src="./screen2.png" />
+
+and capabilities are:
+
+```json
+{
+  "appium:unlockType": "pattern",
+  "appium:unlockKey": "729854163"
+}
+```
+
+## Mid-Session Unlock
+
+There is also a possibility to interact with the device's lock screen while the test session is running.
+Use the following mobile extensions for this purpose:
+
+- [mobile: lock](../../README.md#mobile-lock)
+- [mobile: unlock](../../README.md#mobile-unlock)
+- [mobile: isLocked](../../README.md#mobile-islocked)
