I am currently running Ubuntu GNOME 15.10 with GNOME 3.18, though I used to (a long while back) run Windows 7, and though Ubuntu is better in most ways, there is still a feature lacking or at least a feature which I haven't found yet...
Is there any way of making it so that on the locked/login screen after a certain number (defined by me) of incorrect password attempts it doesn't allow the user to enter their password for a certain amount of time (defined by me) and also logs this to a log?
So for instance if a user enters an incorrect password 3 times they are not allowed to try again for another 5 minutes and this is also logged to a log defined by me.
It would also be useful if I could also optionally make it so that say the user tries to enter their password and gets it wrong 2 times, if they within the next 5 minutes try again it locks them out for 5 minutes, however if they try again after 5 minutes have gone the counter of incorrect password attempts is reset back to 0.
Is there already such a feature? Or perhaps a way of manually implementing it with a script or something?
