AutoOK7 cydia tweak makes using text based lockscreen passwords easier.
It automatically unlocks your device the moment you get your password right, much like the number based password does. With AutoOK you no longer have to press “OK” when you finish typing in your password. This allows you have more complex passwords while still retaining the ease of use that number based passwords grant you.
IMPORTANT: Please follow the instructions in the settings pane to enable the tweak
