Tokens can be brute forced if 'Clear failcounter after minutes' is not zero #1578

It appears that if 'Clear failcounter after minutes' is set to a non-zero value, after that timeout expires, any token can be brute forced.

I believe one of two options could be pursued to mitigate this.

Option #1 (more security, less user-friendly):
After the failcounter is exceeded, any additional failed attempt will 'reset' the fail exceeded counter and restart the timeout.

Option #2 (more user-friendly):
After the failcounter is exceeded, truly reset the failcounter to 0 so that the user would have more attempts before they are locked out again.

I believe #1 would be easier to implement programatically.

Thanks! Actually we already fixed this here
We developed a work-around using event handlers, which we will publish shortly.

@droobah here is the workaround:
