This MOD is discontinued, but the features can be found in LockScreen Tweakbox. use that MOD instead
This module will give you 20 attempts on the lockscreen rather than 5. I might add the option to change this amount, depending on how popular this tweak proves to be. Also, I'm planning on making a lockscreen tweakbox which will include this and much more.
APK is attacthed and also on Xposed Repo
After 5 attempts, you will still get the normal alert to wait 30 seconds, but this mod will disable the wait, so once you dismiss the laert you can try again instantly. However, after 20 attempts, you will have to sign in with your Google Account as normal, will add an option to disable this too!
