Octopus Authenticator for Android version 4.1.2 enables Authentication approval directly from push notifications. 

Android users can now approve authentication requests directly from the push notification. Depending on the current user interaction with the device an Authentication dialog appears either directly on the screen or as a notification. Tapping the notification opens the Authentication dialog over the existing screen. If the device is locked, the screen will turn on and display the Authentication dialog above the wallpaper.

For more information please refer to the attached Release Notes.

The version can now be downloaded from Google Play
