I'd like to suggest 2 features, both of which I think require minor effort but would be useful to your userbase.
First, can you add a "button" to generate a new user password? The system will generate one during setup but I would like to be able to generate a new password on demand.
Second, we have some users who think password are mostly an inconvenience. So we quite often see passwords like, "1234", "123456", and my personal favorite for those extremely security conscious, "bob1". You get the point... Of course every time on of these accounts gets cracked we have to deal with blacklists etc to clear it up.
Can we have a "password check" feature that could, for example, at least check to make sure the password contains X CAPITAL letters, X numbers.
Ideally this is a process that could run daily (or whatever interval) and send an email to offenders letting them know they need to change their password or the account will be suspended (message should be configurable). The Cadillac version would automatically followup at a pre-determined interval (say you give them 2 days to do the update), then if not changed by the user it would automatically change the password to something more secure.
I hope that makes sense!
