At this moment it is only possible to set the password strenght for the entire application.
It would be nice to do this per user of usergroup
For example:
We have users at the office which we want to use the higher password strength but also users in our warehouse wich we want to use al lower strenght because the are only using a simple scanning device (just a digit code as inlog).
Now we are forced to use the lowest strengt for everybody.
